Ten Years of Shortleaf Pine Seed Crops in Texas
Abstract:This paper presents examples of a forest type that seems safe, i.e., dant seeding in two of 10 years, almost none in the other six. Good crops coincided with reported seed years throughout much of the species range in Texas. Partial cuttings two to nine years before seedfall stimulated production on residual trees during seed years, but had no effect in other years. Production per tree was best where large-crowned trees were released. Seed quality was highest when crops were heaviest. On the average, 61 percent of the seeds were sound. Clearcut strips up to two chains wide received adequate seed from adjacent stands, but adequacy beyond three chains is problematical. Infrequency of seedfall and frequency of summer droughts suggest that natural regeneration in Texas shortleaf often needs to be supplemented by artificial means.
