Much of the original ecosystem had been cleared for farming. Since then, the community has been rapidly built up by subdivisions, businesses, and mixed land use — and thus very little of the area represents its native ecosystem.
Most of the core Klein area sits between Spring Creek to the north, separating Tomball to the northwest by Willow Creek, and Cypress Creek is the waterway that passes through the center of the greater Klein area. Both these creeks are tributaries to lower Spring Creek (Harris County, Texas) and ultimately Lake Houston.
Parcels along Cypress Creek contain a mix of older undisturbed bottomland forest, private residence, and well-maintained bike trails through public parks.
Prairie-like stretches of oak (Quercus virginiana) and various hardwoods, draped in Spanish moss, are present in and around the Raveneaux Country Club, Klein High School, as well as in public spaces such as Meyer Park.
A well-preserved oxbow lake habitat can be found in the Ponderosa Walking Park. Dwarf palmetto Sabal minor and southern magnolia Magnolia grandiflora trees are found in the understory and near the edges of bodies of water and swamps, as well as bald cypress (Taxodium distichum) sweetgum (Liquidambar styraciflua), water oak (Quercus nigra), and black tupelo (Nyssa sylvatica) all being present.
Reptiles from common species like the Red-ear slider turtle, and green anole (Anolis carolinensis), American green tree frog, to more precarious species such as the venomous Texas coral snake Micrurus tener, and the American alligator.
