Forage biomass of 22 shrub species from Monfragüe Natural Park (SW Spain) assessed by log–log regression models

摘要: Abstract The forage productivity of 22 species bushes was studied in the protected area Monfrague Natural Park (South-Western Spain). In all cases, same methodology used, consisting determination biomass plants and its relationship with best correlated size variable, by means log–log regressions. variables measured were total height ( H ), relative (RH), minimum D 1 ) maximum 2 diameters, canopy (CA) volume (CV). For each species, a regression model built, giving values R coefficients, ANOVA test values, average standard deviations residuals fitting Gaussian distribution Kolmogorov–Smirnov test. All tests satisfactory suggesting that proposed equations can be reliably used for carrying capacity this semi-arid ecosystem red deer Cervus elaphus , L) management.
