Native Prairie Restoration within Old World Bluestem AMANDA LIGHTSEY

Project Objectives

Re-establishment of native grass impossible without addressing problematic and aggressive invasive exotic species, such as: 

Kleberg bluestem (Dichanthium annulatum)

King Ranch bluestem (Bothriochloa ischaemum).


Hypothesis

Kleberg and King Ranch bluestem are not overly tolerant of shade 

Total removal of established Kleberg & King Ranch, over-seeding to reintroduce natives.

Plant robust, high biomass natives such as switchgrass (Panicum virgatum) to create shade, over-seed to reintroduce natives
