LINPI conserves biodiversity by preserving the genetic heritage of Long Island’s native plant populations. This is accomplished by establishing commercial sources of local ecotypic (i.e. genetically native) seed and plants for native plant production, contributing to a regional seed bank, fostering a demand for native plants and serving as a propagation resource for the nursery industry. There is a focus on capturing as much genetic variation as possible when collecting and propagating plant material while minimizing the ecological impacts of harvest.
