Allow shrubland to regenerate without active management
A replicated, paired, site comparison study of seven shrublands that had been previously burned in New Mexico and Texas, USA (Ahlstrand 1982) found that sites that were allowed to recover without active restoration had a similar shrub cover to unburned sites, but higher grass cover. Shrub cover did not differ between sites after seven years (burned: 7%; unburned: 9%). After seven years of recovery grass cover was higher (53%) than in unburned sites (35%). Seven sites that had been burned between three and seven years ago and seven paired unburned sites were selected. Plant species and their percentage cover were recorded within fifty 0.1 m2 plots/site.
