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.
