Primary vegetation includes the
Ashe juniper (often called
mountain cedar), several different species of oak,
bigtooth maple,
American sycamore,
escarpment black cherry,
Texas ash,
yellow-flowered red buckeye,
mesquite,
Texas persimmon,
Texas mountain-laurel,
Texas madrone, redbud, wild grape,
prickly pear,
Virginia creeper and various types of brush, grasses, and ferns. Bigtooth maple colors are brilliant if autumn is droughty, or has cold nights, but are more muted in a mild, damp autumn.
Texas red oak gives a fine crimson display almost every year and may retain its leaves well into winter. The Natural Area is most crowded when the fall colors peak in late October-early November. Evidence suggests that the maple trees that give the preserve its name are
relics: remnants of a larger, more widespread population that flourished during the cooler and wetter climate of the
last glacial period. Today, their distribution is limited by the relative rarity of the
soils and
microclimates they require to thrive. A more extensive list of the preserve's fauna and flora can be found at the LMSNA Ranger Station. == Recreation ==
