Cedar (Ashe Juniper) Infestation
Ashe juniper — what locals call cedar — is native to the Hill Country but spreads into pasture and around oaks when left unmanaged, crowding out native grasses. Cedar doesn't resprout from the stump once it's cut below the green. New cedar comes back from seed carried in by birds and wildlife from cedar still standing nearby, so a maintenance pass every few years keeps regrowth small.
