[2] From 2016 through 2020, a pair of bald eagles (Haliaeetus leucocephalus) has nested in a large eucalyptus tree near Felt Lake and the preserve.
The trails at Arastradero Preserve include Acorn, Arastradeo Creek, Bay Laurel, Bowl Loop, Juan Bautista de Anza, Meadowlark, Ohlone, Paseo del Roble, Portola Pastures, Redtail Loop, Wild Rye, Woodland Star, and Woodrat.
[2] Grassroots Ecology, a local environmental nonprofit, has run a collaborative stewardship program on the preserve in cooperation with the City of Palo Alto since 1997.
Volunteers and Grassroots Ecology staff work to improve the Preserve by eliminating invasive weeds such as non-native thistles, planting native species such as blue wild rye and engaging local youth and community members.
There remains a small piece of private property adjacent to Arastradero Road surrounded on all sides by the preserve which currently has no structures.
