  1. Plant native species

    A replicated, site comparison study in 2001 in grassland in Texas, USA (McIntyre 2003) found that Texas horned lizards Phrynosoma cornutum were present in reseeded native and non-native grassland. Texas horned lizards were observed in one reseeded native grassland plot planted without buffalo grass Buchloe dactyloides (one lizard), in one reseeded native grassland plot planted with buffalo grass (one lizard) and two reseeded non-native grassland plots (one lizard/plot). In July 2001, Texas horned lizards were opportunistically surveyed in 1 km2 plots reseeded with either a native species mix excluding buffalo grass (4 plots), a native species mix including buffalo grass (4 plots), or non-native grasses (weeping lovegrass Eragrostis curvula or Old World bluestem Bothriochloa ischaemum, 7 non-native grass plots), as well as a single plot of unseeded unploughed native grass (16 total plots). Reseeded plots were part of the US Conservation Reserve Program to restore prairie.
