%description
Provides functions for probability and non-probability sampling design,
sample selection, and population estimation tailored to natural resource
management. Probability methods include simple random sampling, stratified
sampling, systematic sampling, cluster sampling, and
probability-proportional-to-size sampling. Non-probability methods include
convenience, judgement-based, and quota sampling. Estimation functions
cover means, totals, ratio estimators, regression estimators, and the
unequal-probability estimator of Horvitz and Thompson (1952,
<doi:10.2307/2280784>) for unequal-probability designs. Utilities support
biomass, soil-loss, and carbon-stock estimation from field plots. Spatial
extensions provide random, systematic, stratified, and raster-weighted
sampling within geographic polygons using the 'sf' and 'terra' packages,
with extraction of remote-sensing covariates at sample locations.
Applications include forest inventory, soil erosion monitoring, watershed
studies, and ecological field surveys.
