Abstract:
The representativeness of the inventory of shrub species of a natural protected area in Coahuila, Mexico was analyzed, with the following objectives: to describe the types of sampling bias; to define the environmental heterogeneity of the botanical records; to determine the level of spatial resolution that supports the information collected. Biases were significant (χ2=distance road 199.01; p<0.01, by altitudinal range χ2=391.02; p<0.01 and vegetation χ2=518.13; p<0.01). The inventory sample exhibits significant differences between the control group and a randomized design for 5 bioclimatic variables (mean annual temperature (Bio1): U=117,900; p<0.01; isothermality (Bio3): U=189.650, p<0.01; precipitation wettest month (Bio13): U=134.330, p<0.01; seasonality of precipitation (Bio15): U=175.720, p<0.01 and precipitation of the coldest quarter (Bio19): U=146.550, p<0.01). Environmental variables and road distances, on the coverage of this infrastructure in the area, can contribute to a good characterization of the ANP. The information from collected records is adequate for small scales of analysis (1 and 0.5°).
