Stand structure and climate influence on the growth trends of a marginal forest population of Pinus nigra spp. nigra

<p>The Black pine of Villetta Barrea (<em>Pinus nigra</em> ssp. <em>nigra</em> var <em>italica</em>) is a variety of the <em>nigra </em>subspecies. It is naturally distributed only in the Abruzzo Region, near the village of Villetta Barrea, with...
