Location: Templeton, PA
Description: The Armstrong Trail south of Templeton was created on a railroad bed paralleling the Allegheny River, passing between a steep wooded hillside and a large wetland complex. The north-facing wooded slope contains a rich plant assemblage characteristic of a sugar maple-basswood forest. The large trees and north-facing aspect of the slope provide a cool moist habitat that supports a rich spring wildflower community. Among the rich diversity of plants at this location is a large population of the PA-threatened plant species of concern, harbinger-of-spring (Erigenia bulbosa). This small, delicate plant is one of the earliest-blooming wildflowers in Pennsylvania, with the flowers generally appearing from March into early April. The Templeton parking area for the Armstrong trail is at mile marker 53.9.
From turkeys, turkey vultures, tiny finches to majestic bald eagles, Armstrong Trails provides the opportunity to see and study dozens of native bird species. In 2020, several eagle nests were spotted, keep an eye to the sky.

Location: Armstrong County, PA
Description: Keystone Lake comprises 850 acres stretching 5.5 miles and is the largest lake in Armstrong County. The lake contains shallows and wetlands, and gets as deep as 90 feet. The northern end of the lake has emergent vegetation that provides suitable breeding habitat for wetland birds including species of concern, Sora (Porzana carolina), and Virginia Rail (Rallus limicola). Both of these secretive species return in the spring to use wetlands with cattails and other emergent vegetation for breeding. Virginia Rails and Soras build nests over the water supported by wetland vegetation, while the shallow areas are used for foraging for seeds and invertebrates.
Keystone Lake provides an excellent warm water fishery with large and small mouth bass, walleye, musky, perch, crappies, bluegills, sunfish, and trout (stocked).

The Indiana bat and Pennsylvania fence skink, as well as bald eagles, coyotes, black bear and blue heron can be found.
