Location: Lower Austria Map
Area: 1300 hectares
Thayatal National Park (Nationalpark Thayatal) is one of Austria's smallest yet most biodiverse protected areas, located in the northeastern part of Lower Austria along the border with the Czech Republic. Established in 2000, it spans approximately 13.3–13.6 km² (1,330–1,360 hectares) and forms a cross-border conservation zone with the adjacent Podyjí National Park in the Czech Republic, together covering about 77 km² (7,700 hectares). The park protects one of Central Europe's last near-natural valley landscapes, often called Austria's "Green Canyon," featuring the meandering Thaya River (Dyje in Czech) that carves deep into the Bohemian Massif's crystalline rock, creating dramatic gorges, steep slopes, and a mosaic of habitats. Recognized by the IUCN as a Category II protected area since 2001, Thayatal emphasizes minimal human intervention to preserve its ecological integrity, hosting an extraordinary concentration of species—over half of Austria's native flora in just 0.016% of the country's land area—while offering visitors serene hiking, educational experiences, and glimpses into a pristine river ecosystem.
Thayatal National Park (Nationalpark Thayatal) is Austria’s smallest
national park, covering just 13.3 km² (5.1 sq mi) in the northeastern
part of Lower Austria, right along the border with the Czech Republic.
It protects one of Central Europe’s last largely natural river-valley
landscapes, formed by the Thaya (Dyje) River as it cuts a dramatic,
steep-sided breakthrough valley through ancient crystalline rocks of the
Bohemian Massif. The park directly adjoins the larger Czech Podyjí
National Park (established 1991), creating a transboundary protected
area where nature ignores political borders.
The park is renowned for
its biodiversity in a compact area—about 92% forest, 4% meadows, 3%
water, and 1% dry grasslands/rocks—thanks to varied microclimates, sun
exposure on slopes, and diverse geology. It was officially established
on 1 January 2000 and recognized by the IUCN as a Category II protected
area in 2001. In 2025 it became part of the Transboundary Ramsar Site
“Podyjí – Thayatal National Park, Part Austria.”

Geological and Natural Origins (Millions of Years Ago)
The
valley’s dramatic scenery dates back roughly 5 to 1.5 million years,
when the Thaya River incised up to 150–220 meters deep into the ancient
metamorphic rocks (gneiss, granite, schist, phyllites) of the Bohemian
Massif—the oldest mountain range in Austria, with rocks up to 600
million years old. This created characteristic meanders, gorges, rocky
cliffs, boulder fields, and an “Umlaufberg” (meander mountain, 378 m
high) almost encircled by the river. Near Hardegg, alkaline rocks like
calc-silicate and marble also appear. The park sits at a climatic
boundary between the humid Central European Waldviertel plateau climate
and the more continental, drier Pannonian influence from the east. These
factors produce an exceptional variety of habitats—beech forests on
shady slopes, thermophilous oak forests on sunny ones, and unique
riverine ecosystems—making it a biodiversity hotspot despite its small
size.
Ancient and Medieval Human History
Humans have inhabited
the Thayatal region for thousands of years. Archaeological evidence
points to early Stone Age presence in Lower Austria, followed by Celtic
settlement, incorporation into the Roman province of Noricum, and later
dominance by Germanic Bavarii peoples after the fall of Rome. By the 9th
century, the Frankish Empire controlled the area; from the 10th–12th
centuries it formed part of the Margraviate of Austria.
The most
prominent medieval landmark is Hardegg Castle (Burg Hardegg), first
mentioned around 1145 as a border fortress overlooking the Thaya. Built
by the Counts of Plain and later owned by families such as the
Khevenhüller and Prueschenk (who received the title Counts of Hardegg
from Emperor Maximilian I), it played a role in regional defense. The
surrounding town of Hardegg developed around it. The area saw conflict
during the 15th-century Hussite Wars due to its proximity to Bohemia.
The castle later fell into disrepair but was rebuilt in the 19th century
and remains a key cultural feature within or overlooking the park today.
20th Century: Iron Curtain as Accidental Protector
After World
War I, the Thaya became the border between the First Austrian Republic
and the new Czechoslovakia. During World War II, the region lay within
Nazi-controlled Reichsgau Niederdonau. Post-1945, the border zone was
heavily militarized. In 1948 the communist regime in Czechoslovakia
established a restricted border zone; by 1951 it formed part of the Iron
Curtain. The “death strip” with minefields, watchtowers, and
shoot-on-sight orders severely limited human access and development on
both sides. Ironically, this political division allowed nature to
regenerate into a “secondary wilderness,” preserving forests and
habitats that would otherwise have faced more intensive use. The Velvet
Revolution of 1989 ended the Iron Curtain: the border opened on 9
December 1989, and the Thaya Bridge near Hardegg reopened on Easter
1990, drawing about 10,000 celebrants. The former “death strip” later
became part of Europe’s “Green Belt” conservation initiative.
The
Fight for Protection (1980s–1990s)
Serious conservation efforts began
in the 1980s. In 1984, plans emerged for a hydropower plant at Byči
Skála on the Czech side. Local citizens’ initiatives (notably the
Bürgerinitiative zur Erhaltung des Thayatals) and the municipality of
Hardegg successfully blocked the project through protests and advocacy.
In 1988 and 1991, the Lower Austrian state government designated two
precursor nature reserves (Thayatal I and II) along the river. When the
Czech Republic created Podyjí National Park on 1 July 1991, Austria
committed in 1992 to matching protection levels. A feasibility study
commissioned by the Marchfeldkanal operating company confirmed
viability. In 1995 Lower Austria passed its National Park Law (the first
Austrian national park, the Danube floodplains, followed in 1996). On 26
October 1997, a state treaty under Article 15a of the Federal
Constitutional Law was signed between federal ministers Martin
Bartenstein and Rudolf Edlinger and Lower Austrian Governor Erwin Pröll.
DI Robert Brunner was appointed the park’s first director in 1998, and
administration began in Hardegg in 1999.
Official Establishment
and Development (2000–Present)
The park officially opened on 1
January 2000 (“quiet” start), with full public operations following. A
bilateral Thayatal Commission was founded in 2001 for cross-border
coordination. The same year it received IUCN Category II status. The
Nationalparkhaus visitor center opened in 2003 in Hardegg (designed with
local wood and winning the NÖ Holzbaupreis). In 2003 the park also
earned the Council of Europe’s European Diploma for Protected Landscapes
(renewed multiple times).
Key milestones include:
2007:
Sensational rediscovery of the European wildcat (long thought extinct in
Austria); a wildcat enclosure and “Wildkatzenwanderweg” trail later
became popular attractions.
2009: 10-year anniversary celebrations,
including the opening of the Naturerlebniswelt adventure playground.
2011: First expansion (30 ha of forest) and further wildcat-focused
projects.
2018: Core zones certified as WILDForest (250 ha) and
WILDRiver (2 km of Thaya) by the European Wilderness Society.
2025:
25th anniversary, marked by the bilingual book Zeitzeugen der
Nationalparkentstehung (interviews with key figures from both countries)
and designation as a transboundary Ramsar wetland site on 6 May.
The park has grown through land acquisition, visitor infrastructure,
research (e.g., the “Natur ohne Grenzen” project with the Czech park),
and tourism partnerships. It remains a model of transboundary
cooperation, transforming a once-divided border into a unified
ecological corridor.
Today, Thayatal National Park exemplifies
how political history, citizen activism, and international cooperation
can safeguard extraordinary natural and cultural heritage. Its compact
size belies its ecological richness and symbolic importance as a “green
bridge” between Austria and the Czech Republic—one of the last intact
Central European river valleys. Visitors can explore it via hiking
trails, the Thaya Bridge border crossing, and exhibits at the
Nationalparkhaus, all while witnessing ongoing natural recovery in a
landscape shaped by geology, human history, and fortunate preservation.
Topography and Landforms
The defining feature of Thayatal is its
dramatic breakthrough valley (Durchbruchstal), where the Thaya has
incised a deep, winding gorge into the surrounding terrain. The river
has carved up to 150 meters deep over millions of years, creating steep
slopes, near-vertical rock faces, cliffs, and a striking series of
incised meanders.
The landscape is hilly and rugged, with forested
slopes rising sharply from the riverbanks. Valley bottoms are sometimes
wider and flatter, but the dominant impression is one of confined,
intimate gorges alternating with open meander loops.
A standout
landform is the Umlaufberg (“meander mountain” or “loop mountain”), a
prominent hill approximately 378 m high that is almost completely
encircled by a large bend of the Thaya River—a classic example of an
incised meander formed as the river downcut while maintaining its
sinuous course.
Elevation ranges from roughly 271 m (near the river
level) to a maximum of around 529 m, with an average of 417 m. The
highest named peaks within or immediately adjacent to the park include
Binderberg (~463 m) and others in the 450–480 m range (e.g., Hohe Sulz
~481 m in some references). South- and east-facing slopes tend to be
drier and warmer, while north- and west-facing slopes are shadier and
moister, creating pronounced microclimatic contrasts even over short
distances.
Geology
The park sits on the southern edge of the
Bohemian Massif (Böhmische Masse), one of Europe’s oldest geological
units. The bedrock consists primarily of ancient metamorphic and
crystalline rocks—primarily granite, gneiss, and schist—dating back up
to 600 million years (Precambrian to Paleozoic). These hard, resistant
rocks have allowed the river to form steep, enduring cliffs rather than
broad floodplains.
In places near Hardegg, alkaline rocks such as
calc-silicate and marble also occur, adding further geological variety.
The river’s long-term downcutting (primarily during the Pliocene and
Pleistocene, roughly 5–1.5 million years ago) into this resistant
crystalline basement has produced the characteristic steep-sided, rocky
valley morphology that distinguishes Thayatal from the surrounding
rolling hills of the Waldviertel and Weinviertel regions.
Hydrology
The Thaya River is the lifeline of the park. It is largely
free-flowing and natural, with minimal human modification—2 km of the
river is even certified as a “WILDRiver.” Tributaries (such as the Kaja
stream) join the main river within the park, adding side valleys with
their own steep, forested slopes and small waterfalls or cascades.
The river’s meanders, oxbow-like loops, and occasional gravel bars or
rocky banks create a dynamic riparian zone. Seasonal flooding and the
river’s erosive power continue to shape the valley, maintaining steep
banks, rock slides, and a mosaic of wet and dry habitats along the
water’s edge.
Climate
Thayatal lies at an important climatic
transition zone. To the north and west (Waldviertel influence) the
climate is cooler, more humid, and transitional Central European; to the
south and east (Weinviertel/Pannonian influence) it becomes more
continental, with warmer, drier summers and greater temperature
extremes. This boundary, combined with the valley’s varied slope aspects
and elevation differences, produces an unusually wide range of
microclimates within a very small area.
Precipitation is moderate
(higher on the plateau edges), while the deep valley can trap cooler air
or create sheltered, sunnier pockets. These conditions, layered on top
of the diverse geology and topography, explain the park’s exceptional
biodiversity—over 40% of Austria’s plant species occur here despite the
tiny area.
Landscape Composition and Habitats
Land cover
breaks down roughly as:
92% forest (dense mixed deciduous woodlands
dominated by beech on cooler/moister slopes, oak-hornbeam on
warmer/drier slopes, plus lime, sycamore, and other species)
4%
meadows (both nutrient-rich and poor pastures)
3% bodies of water
(primarily the Thaya and streams)
1% dry grasslands and rocks (steep,
sun-exposed rocky plateaus and cliffs supporting specialized flora)
This mosaic—forests on slopes, dry grasslands on exposed rocks,
meadows on gentler areas, and riparian zones along the river—results
directly from the interplay of geology, river incision, slope
orientation, and climate gradients.
Thayatal National Park (Nationalpark Thayatal) in northern Lower
Austria is Austria’s smallest national park, covering about 13.6 km²
(1,360 hectares) on the Austrian side of the border with the Czech
Republic’s Podyjí National Park. Together they form a transboundary
protected area renowned for exceptional biodiversity in one of Central
Europe’s last near-natural river valleys. The “Green Canyon” along the
free-flowing Thaya (Dyje) River features steep, rocky slopes up to 150 m
deep, dramatic meanders, vertical rock faces, and a mosaic of habitats
shaped by varied geology (primarily granites and gneisses of the
Bohemian Massif with pockets of more alkaline rocks) and a climatic
transition zone.
The park’s flora is extraordinarily rich: the
combined Austrian-Czech protected area hosts around 1,290 vascular plant
species—nearly 40–44% of Austria’s total native flora (approx. 2,950
species)—on just 0.016% of the country’s land area. This diversity stems
from the meeting of Central European (Atlantic-influenced) and
Pannonian-continental climates, plus extreme microhabitat variation from
slope exposure, soil depth, moisture gradients, and the river’s
influence.
Over 90% of the park is forested (>92% in some estimates),
with the remaining area including ~4% meadows (about 63 ha, mostly
narrow floodplain strips along the Thaya and Fugnitz rivers) and ~1% dry
grasslands and rocky outcrops. About 20% of the forests were
historically planted with non-native conifers, but the park management
is actively converting these to natural deciduous communities through
natural succession.
Dominant Forest Vegetation
The forests
form the backbone of the park’s landscape and reflect the east-west
climatic gradient:
Western and northern (shadier, cooler, often
moister) slopes: Beech-dominated forests (Fagus sylvatica) on
lime-influenced or granite substrates. These include rich ravine and
slope forests with sycamore maple (Acer pseudoplatanus), lime/linden
(Tilia spp.), wych elm (Ulmus glabra), and hornbeam (Carpinus betulus).
Indigenous conifers appear sparingly: yew (Taxus baccata), fir (Abies
alba), and juniper (Juniperus communis). Understory herb layers are lush
in nutrient-rich spots, featuring species such as Turk’s-cap lily
(Lilium martagon), mezereon (Daphne mezereum), wood sorrel (Oxalis
acetosella), bulbous toothwort (Cardamine bulbifera), wood melick
(Melica uniflora), and white helleborine (Cephalanthera damasonium).
Eastern and southern (warmer, drier) slopes: Dry-warm oak forests, often
Pannonic oak-hornbeam woodlands (Quercus petraea and Carpinus betulus).
These support more xerothermic (dry-adapted) elements from southeastern
Europe.
Other forest types: Small patches of alluvial alder forests
along the river, relict pine stands (Pinus sylvestris) on rocky
outcrops, and mixed deciduous communities. The forests are largely left
to natural processes, fostering old-growth characteristics with deadwood
and structural diversity.
Open Habitats: Meadows and Dry
Grasslands
The non-forested areas, though small, are botanical
hotspots and require active management to prevent succession back to
woodland.
Meadows (approx. 63 ha): Mostly in the river floodplain;
they vary from nutrient-rich to lean, wet to drier types. Originating
from historical grazing, they are now mown once or twice yearly
(starting mid-June) with insect-friendly equipment to maintain
diversity. They burst with color: orchids (including the lesser orchid),
Carthusian pink/carnation (Dianthus carthusianorum), meadow sage (Salvia
pratensis), daisies, bellflowers (Campanula spp.), and many others.
These support rich insect life (e.g., dozens of grasshopper species and
over 950 butterfly species recorded in the broader area). Seasonal
highlights include spring geophytes like snowdrops (Galanthus nivalis),
hepatica, corydalis, and primroses, shifting to summer blooms of
buttercups, scabious, and bedstraws.
Dry grasslands and rocky
plateaus (~1% of area): These are true rarities on steep, south-facing
slopes and thin-soiled rocky sites with intense sun exposure and rapid
drainage. Vegetation progresses from rock-dwelling specialists and
stone-chipping grasslands to dwarf-shrub heaths (e.g., Scotch
heather/Calluna vulgaris), closed grass steppes, and forest-steppe
transitions. Paradoxically species-rich because harsh conditions favor
modest specialists over competitive generalists. Key rarities here
include the high pearl grass and soft-haired feather grass (Stipa spp.),
found nowhere else in Austria, plus colorful displays of
variegated/Hungarian iris (Iris variegata), meadow pasque flower
(Pulsatilla spp.), spring draba (Draba spp.), and more.
Notable
and Rare Plant Species
Several plants are highlights or have unique
status in the park:
Siberian melic grass (Melica altissima) — The
only known Austrian population grows in the dry grasslands and forest
steppes here; it can reach 2 m and has distinctive side-tilted,
pearl-like flower clusters.
Yellow lady’s slipper orchid (Cypripedium
calceolus) — One of the largest native orchids in Austria, with its
iconic slipper-shaped flowers and specialized pollination trap.
Turk’s-cap lily (Lilium martagon) — Thrives in the cool shade of
nutrient-rich forest understories; its turban-shaped flowers are
striking.
Cornelian cherry (Cornus mas, also called yellow cornel or
“Dirndl”) — An inconspicuous early-spring shrub whose bright yellow
flowers blanket areas like the Umlaufberg before leaves emerge; its
late-ripening fruits provide vital food for wildlife.
Variegated iris
(Iris variegata) — Fragrant rhizomes and attractive flowers; a Pannonian
element.
Other rarities include the recently discovered plantain
thrift and various xerothermic specialists from the Alps’ foothills or
southeastern Europe.
Neophytes and Conservation Notes
Roughly
one-third of Austria’s plant species include neophytes (post-1492
introductions). The park records 116 of about 1,300 such species
nationwide (e.g., horse chestnut, lupin, agricultural crops). Most
coexist harmlessly; only a few are invasive and actively
monitored/controlled (black locust, Indian knapweed, Japanese knotweed,
Russian hogweed).
The park’s management emphasizes minimal
intervention in forests (natural succession) and targeted mowing/grazing
mimics in open areas to preserve the high-diversity mosaic. This small
but botanically dense landscape exemplifies how geology, climate, and
river dynamics can concentrate immense floral richness in a compact
area.
Thayatal National Park (Nationalpark Thayatal) in northeastern
Austria is the country's smallest national park, covering about 13.3 km²
(1,330 ha) on the Austrian side. It forms a transboundary protected area
with the larger Podyjí National Park in the Czech Republic, together
preserving one of Central Europe's last near-natural river valley
landscapes along the Thaya (Dyje) River.
Despite its compact size,
the park supports exceptional faunal diversity—thanks to dramatic
topography (steep gorges, meanders, cliffs, rocky slopes, and
floodplains), a mix of deciduous forests, dry grasslands, and an intact
river ecosystem, plus its position at the climatic transition between
cooler, wetter Central European conditions and warmer, more continental
Pannonian influences. This creates a mosaic of habitats that supports
species from both biogeographic zones, including many rare or endangered
ones that have persisted or returned after the Iron Curtain opened.
The park is a true biodiversity hotspot: the Austrian portion alone
hosts over 950 butterfly species, 20 bat species (nearly three-quarters
of Austria's total), more than 100 bird species, and numerous protected
reptiles, amphibians, and invertebrates. Larger mammals like the
European wildcat have made a celebrated comeback.
Mammals
The
European wildcat (Felis silvestris) is the undisputed flagship and
"star" species. Thought extinct in Austria for decades, it was
rediscovered here in 2007 via camera traps and genetic confirmation—a
major conservation success. The shy, forest-dwelling cat prefers
undisturbed deciduous woodlands with plenty of deadwood and structural
diversity. The Thayatal population is small but potentially viable
(estimates suggest capacity for 15–20 individuals as a core for regional
recovery). Telemetry studies track their movements, and visitors can
observe two habituated wildcats (Frieda and Carlo) in a large enclosure
at the National Park House in Hardegg.
Other mammals include the
European otter (Lutra lutra), which thrives in the clean Thaya River and
its tributaries, feeding on fish and crayfish. Traces of beaver activity
are also noted. Common forest species—roe deer, red deer, wild boar,
foxes, and various small mammals—occur throughout. Occasional sightings
of elk (Alces alces) have been recorded since the border opened. The
park's 20 bat species (including the first Austrian record of Alcathoe's
bat, Myotis alcathoe) indicate high-quality habitats with old trees,
caves, and river corridors for roosting and foraging.
Birds
Over 100 bird species (with higher counts in the binational area,
including ~129–150 breeding or recorded) make the park attractive for
birdwatchers. The black stork (Ciconia nigra) is a highlight: this tall,
elegant wader fishes in the Thaya, especially visible between Hardegg
and the Überstieg viewpoint in early mornings or before noon. Unlike the
more common white stork, it prefers forested river valleys.
The river
and forests support white-tailed eagles (Haliaeetus albicilla) as winter
guests, drawn to the ice-free stretches. Eagle owls (Bubo bubo) and
common ravens (Corvus corax) nest on cliffs and rocky sites. Woodpeckers
are well-represented (8 of Austria's 10 species, including the rare
white-backed woodpecker, Dendrocopos leucotos). Other notables include
collared and red-breasted flycatchers, various raptors (hobby,
peregrine), kingfishers, and dippers along streams.
Reptiles
The park's dry grasslands, rocky outcrops, and warm south-facing slopes
are prime reptile habitat, making it a national hotspot for several
endangered species.
Eastern green (emerald) lizard (Lacerta
viridis): One of Austria's strongest populations. In early May, males
display vibrant green and blue colors during mating season at viewpoints
like Überstieg and the Max plateau—an impressive spectacle.
Dice
snake (Natrix tessellata): A highly protected, fish-eating water snake
tied to the river and banks.
Aesculapian snake (Zamenis longissimus):
Europe's largest non-venomous snake, often found in forests.
Smooth
snake (Coronella austriaca): Another secretive forest species.
Others: grass snake (Natrix natrix), slow worm (Anguis fragilis), and
occasional sand lizard (Lacerta agilis).
Amphibians
The intact
river ecosystem and wetlands support crested newts (Triturus cristatus,
or Kammmolch), along with other amphibians in ponds, streams, and damp
forests. These benefit from the park's low-disturbance zones.
Aquatic Fauna (Fish and Invertebrates)
The Thaya River is a key
lifeline. The noble crayfish (Astacus astacus)—once widespread but now
threatened with extinction in Austria—finds a vital refuge here in
clean, well-oxygenated waters. Fish species (e.g., brown trout,
grayling) sustain the food web for otters, birds, and crayfish.
Insects and Other Invertebrates
Invertebrate diversity is staggering.
The stag beetle (Lucanus cervus) is iconic: its larvae develop for 5–8
years in decaying oak wood and rootstocks before the impressive males
emerge with large mandibles.
The park's >950 butterfly (and moth)
species reflect the mosaic of meadows, forest edges, and grasslands—many
are rare or localized. Other beetles, grasshoppers, and aquatic
invertebrates thrive in deadwood-rich forests and the river.
Conservation and Viewing Notes
The park emphasizes minimal
intervention, allowing natural processes while protecting sensitive
species. Many animals are elusive (wildcats, snakes, woodpeckers), but
patient hikers may spot black storks, lizards, or butterflies along
trails like the Wildkatzenweg. The visitor center offers exhibits, the
wildcat enclosure, and guided tours (including bat nights). The
transboundary nature aids species like wildcats and lynx as a migration
corridor.
Managed independently but collaboratively with Podyjí National Park, Thayatal prioritizes species conservation, genetic diversity, and natural processes with minimal intervention. Goals include preserving ecosystems for free development, adhering to IUCN Category II standards. The park counters threats like historical development pressures through strict zoning (e.g., 90.7% nature zone) and certifications emphasizing wilderness. Joint Austrian-Czech efforts exemplify international cooperation, focusing on habitat restoration, monitoring (e.g., wildcat presence), and sustainable tourism to protect biodiversity for future generations.
Thayatal is ideal for nature enthusiasts, with activities centered on
hiking, education, and wildlife observation. The National Park House in
Hardegg (Merkersdorf 90, 2082 Hardegg; +43 2949 7005;
office@np-thayatal.at) serves as the hub, offering exhibitions like
"Natur-Stories," a café, adventure playground, e-bike rentals,
ranger-guided tours, and a 450 m² wildcat enclosure featuring cats Carlo
and Frieda. The Wildkatzencamp provides accommodations for groups with
ranger-led programs, including forest adventures and evening activities.
Popular trails include:
Einsiedlerweg Circular Trail: 5 km, easy,
through forests and along the Thaya.
Hardegg Castle Loop Trail: 5 km,
easy, with river views and castle sights.
Devil’s Canyon Trail: 8 km,
moderate, featuring rock formations and rare plants.
Ruins of Kaja
Castle Trail: 6.5 km, moderate, exploring ruins and botanic rarities in
Kajabachtal.
Altenburg Ruins Trail: 10 km, moderate, with panoramic
views.
Thaya River Loop Trail: 4 km, easy, family-friendly with
waterfalls.
Guided seminars, school project weeks, and events
emphasize environmental education. The park promotes sustainable visits,
with access on foot or bike across the border.
Thayatal stands out for its cross-border integration, creating a unified protected landscape that transcends political boundaries. Its "impressive silence," high species density, and features like the Umlaufberg (a river-encircled mountain) make it a haven for tranquility and discovery. As a model of binational conservation, it highlights how ecological systems ignore borders, fostering biodiversity in a compact, accessible area.
