Description
Abstract. -- Zapata bladderpod (Lesquerella thamnophila) is an endangered plant found in eight populations in Starr and Zapata counties of southern Texas. The spatial associations between Zapata bladderpod and other plants at one location in Starr County, Texas, between 1997 and 2003 were investigated. Based on densities at sampling plots, the mean population of Zapata bladderpod at the 18.2 ha study site was 3,146 with a high of 8,351 in July 1997 and a low of 826 in March 2001. Zapata bladderpod demonstrated a clumped distribution and significant nonrandom association with associate (P 0.01) and canopy plants (P 0.01). Most Zapata bladder-pods (70.3%) were classified as mature and vegetative. Of all Zapata bladderpods sampled, 18.3% were in fruit, 10.2% were characterized as young plants, and 1.2% were in flower. Considerations for future research are discussed. **********
