Move slowly, speak softly, and observe without disturbing.
Give wildlife plenty of space. Never feed or approach wild animals.
Each encounter is an opportunity to remember we're part of something larger.

Discover the rich biodiversity of the Laguna de Santa Rosa, the largest freshwater wetland complex in the San Francisco Bay Area. This easy trail winds through oak woodlands, riparian corridors, and seasonal wetlands.

Ardea alba
These elegant, all-white wading birds are a stunning sight along the Laguna de Santa Rosa. Standing up to 3 feet tall with a wingspan of nearly 5 feet, Great Egrets move gracefully through shallow waters, hunting fish and frogs with their long, dagger-like yellow bills. Once nearly hunted to extinction for their plumes, they've made a remarkable comeback.
Habitat
Shallow wetlands, marshes, and along the Laguna de Santa Rosa. Often seen wading in still water.
Best Time
Year-round, especially active during early morning and evening hours

Branta canadensis
The Canada Goose is one of the most recognizable waterfowl in North America, with its distinctive black head and neck, white chinstrap, and brownish-gray body. These highly social birds are known for their V-formation flying and loud honking calls. In California's Laguna region, they are year-round residents, thriving in the wetlands and open grasslands.
Habitat
Lakes, ponds, rivers, wetlands, and grassy areas near water. Often seen grazing in parks and agricultural fields.
Best Time
Year-round, especially active during morning and evening feeding times
Buteo lineatus
A beautiful woodland hawk commonly seen and heard throughout Sonoma County. The Red-shouldered Hawk has distinctive reddish-brown shoulders and a boldly banded tail. Their loud, repeated 'kee-ahh' calls echo through the oak woodlands, often mimicked by Blue Jays. These versatile hunters prey on small mammals, amphibians, reptiles, and crayfish.
Habitat
Riparian woodlands, oak forests, and suburban areas near water
Best Time
Year-round resident, most vocal during breeding season (February-May)

Ambystoma californiense
This stunning black salamander with bright yellow or cream spots is one of California's most endangered amphibians. They spend most of their lives underground in rodent burrows, emerging only on rainy nights to breed in seasonal pools. The Laguna de Santa Rosa is one of their critical remaining habitats, making it a vital conservation area.
Habitat
Underground in grasslands, emerging to breed in seasonal ponds and vernal pools
Best Time
Rainy nights from November through February during breeding migration
Lontra canadensis
Playful, curious, and intelligent, River Otters have returned to the Laguna de Santa Rosa after being absent for decades. These charismatic mammals are often seen sliding down muddy banks, wrestling with each other, and hunting fish in the waterways. Their presence indicates improving water quality and ecosystem health in the Laguna.
Habitat
Rivers, streams, ponds, and wetlands with clean water and abundant fish
Best Time
Year-round, most active at dawn and dusk. Look for them in open water areas.
Lynx rufus
The Bobcat is California's most common wild cat, though they're rarely seen due to their secretive nature. These skilled predators patrol the edges of meadows and woodlands, hunting rabbits, rodents, and birds. With their distinctive spotted coat, tufted ears, and bobbed tail, they're beautiful additions to the local wildlife community.
Habitat
Woodland edges, brushy areas, and grasslands. Requires cover for stalking prey.
Best Time
Dawn and dusk, year-round. Occasionally spotted during the day in quiet areas.
Pachydiplax longipennis
Our namesake! The Blue Dasher is a stunning dragonfly with brilliant blue coloring on males and a green-yellow pattern on females. These aerial acrobats are masters of flight, capable of hovering, flying backwards, and catching prey mid-air. They're essential members of our ecosystem, controlling mosquito populations and serving as indicators of water quality.
Habitat
Found near ponds, streams, and our irrigation areas. They prefer still or slow-moving water with plenty of vegetation.
Best Time
Late spring through early fall, most active during warm, sunny afternoons

Ardea alba

Their loud, repeated 'kee-ahh' calls echo through the oak woodlands, often mimicked by Blue Jays. These versatile hunters prey on small mammals, amphibians, reptiles, and crayfish.
Pelecanus erythrorhynchos
These magnificent birds are one of North America's largest, with wingspans reaching 9 feet. Unlike Brown Pelicans, White Pelicans don't dive for fish—instead, they work cooperatively in groups, herding fish into shallow water where they can scoop them up. Seeing a flock of these enormous white birds soaring overhead is an unforgettable sight.
Branta canadensis
The iconic Canada Goose is a familiar sight and sound throughout the Laguna wetlands. Their distinctive honking calls and V-formation flights signal the changing seasons. These large waterfowl mate for life and are devoted parents. While some populations are resident year-round, others still make impressive migratory journeys along the Pacific Flyway.

Ambystoma californiense
This stunning black salamander with bright yellow or cream spots is one of California's most endangered amphibians. They spend most of their lives underground in rodent burrows, emerging only on rainy nights to breed in seasonal pools. The Laguna de Santa Rosa is one of their critical remaining habitats, making it a vital conservation area.
Syncaris pacifica
This tiny, nearly transparent shrimp is found nowhere else on Earth except in a handful of coastal streams in Marin, Sonoma, and Napa counties. The Laguna de Santa Rosa is one of their last remaining strongholds. These endangered creatures are indicators of healthy stream ecosystems and play important roles in the aquatic food web.
Limnanthes vinculans
This delicate white wildflower with yellow centers exists only in the wet meadows and vernal pools around Sebastopol. Listed as endangered, Sebastopol Meadowfoam blooms in spring, creating carpets of white in its remaining habitat. Conservation efforts in the Laguna de Santa Rosa help protect this beautiful and rare endemic species.
Lontra canadensis
Playful, curious, and intelligent, River Otters have returned to the Laguna de Santa Rosa after being absent for decades. These charismatic mammals are often seen sliding down muddy banks, wrestling with each other, and hunting fish in the waterways. Their presence indicates improving water quality and ecosystem health in the Laguna.
Urocyon cinereoargenteus
The Gray Fox is the only canid in North America that can climb trees, thanks to its rotating forearms and strong, hooked claws. These beautiful foxes have grizzled gray coats with rusty red along their sides, ears, and legs. They're more secretive than their red fox cousins and prefer woodland habitats where they hunt rodents, rabbits, and berries.
Canis latrans
The song of coyotes at dusk is one of the quintessential sounds of ranch life. These highly adaptable canids are intelligent, social animals that play important roles in our ecosystem by controlling rodent and rabbit populations. While often heard, they're shy around humans and maintain their distance. Their presence connects us to the wild heart of the landscape.
Neovison vison
Sleek and secretive, the American Mink is a semi-aquatic predator found along the waterways of the Laguna. With their rich, dark brown fur and excellent swimming abilities, they hunt fish, crayfish, frogs, and small mammals. Though rarely seen due to their shy nature, minks are important predators in wetland ecosystems.
Taxidea taxus
These powerful, low-slung digging machines are grassland specialists, perfectly adapted for pursuing ground squirrels and other burrowing prey. With their distinctive black and white striped face and incredibly strong forelimbs, badgers can dig faster than any other mammal. They're primarily nocturnal and leave characteristic large burrows in open areas.
Lynx rufus
The Bobcat is California's most common wild cat, though they're rarely seen due to their secretive nature. These skilled predators patrol the edges of meadows and woodlands, hunting rabbits, rodents, and birds. With their distinctive spotted coat, tufted ears, and bobbed tail, they're beautiful additions to the local wildlife community.
Puma concolor
Also known as cougars or pumas, Mountain Lions are the largest wild cats in the region. These powerful, solitary hunters require large territories and healthy deer populations. While sightings are rare, their presence in the surrounding hills indicates a healthy, intact ecosystem. They typically avoid humans and are most active at night.
