In general, "utilization" of resources on the property is subject to a reasonableness test. A life tenant with dominium directum of an estate may make reasonable use of resources, which means roughly renewable or trivial usage: the culling of firewood in the midst of an expansive forest, or the extraction of coal sufficient for home use from a fecund mine. Any commercialization (e.g. selling rights to the coal shaft) or large-scale exploitation (raising extensive erections on the estate using the timber resources) will implicate the dominium utile reserved to the holder in reversion and be subject to legal action at common law.
