The reserve acts as a critical corridor for the rare silver-studded blue butterfly.
The site hosts a notable variety of carnivorous plants, including sundews, in its wetter boggy patches.
Management includes periodic controlled burning and cattle grazing to prevent the encroachment of scrubland.
The common's sandy soil is the result of ancient geological deposits from the Bagshot formation.
Wisley Common, managed by the Surrey Wildlife Trust, is a expansive heathland habitat spanning significant portions of the Ockham and Wisley commons. The site is a Site of Special Scientific Interest (SSSI) due to its diverse lowland heath and acid grassland ecosystems. It features extensive walking trails winding through pine forests, heath, and ponds. The area supports rare wildlife, including the Dartford warbler and several species of dragonflies. Visitors encounter a landscape shaped by historical grazing and long-term ecological conservation efforts. The common is frequently connected to the adjoining Chatley Heath and Ockham Common, forming a vast, contiguous natural network. The terrain is largely level but can be uneven due to the natural sandy soil of the heathland. It serves as a vital sanctuary for ground-nesting birds during their breeding seasons.

Bring sturdy, waterproof hiking boots, as the paths can become muddy and sandy.
Use insect repellent during late spring and summer months to avoid ticks in the tall grass.
Keep dogs on short leads during the ground-nesting bird season to protect sensitive habitats.
Stepping into fenced-off conservation areas or boggy depressions which can be deeper than they appear.
Stick to marked trails to protect sensitive flora and ensure ground-nesting birds are not disturbed.
