Longleaf pine (Pinus palustris) ecosystems are the subject of restoration efforts in the Southeastern region of the United States. Close to 62,000 hectares of longleaf pine were planted in 2014 alone. Longleaf pine ecosystems contain an abundance of biological diversity, both floral and faunal. Longleaf pine can withstand perturbations such as experienced in hurricane event better than the two other southern pines, loblolly Pine (Pinus taida L.) and slash pines (Pinus elliottii Engelm). Longleaf pine can live for over 400 years. This long lifespan requires it to face large variations in climate, insects and diseases. As it grows over such a long lifespan, it is worth considering if planted longleaf pine provides an avenue for carbon sequestration. In this Special Issue, we explore the potential quantity of C sequestered by longleaf pine and the biotitic and abiotic challenges that face the species.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Title: Nursery culture treatments enhance height growth of outplanted longleaf pine seedlings

Abstract: Longleaf pine (Pinus palustris, LLP) seedlings often remain in the grass stage for several years. This study tested the effect of nursery production treatments on reducing time in the grass stage for LLP. Seedlings were grown in a randomized complete block design with 4 container cavity volume x 2 copper root modifying x 3 N rate x 3 replicate. Fifteen LLP seedlings from each production treatment were outplanted to a randomly assigned row within each of the 3 blocks at the Kisatchie National Forest. Seedling field performance was monitored for six years and root system architecture was assessed in years 2 and 6.

Abstract: Young longleaf pine experience severe scorch during prescribed fire. Between scorch and recovery, the potential exists for decreases in carbon fixation and growth. Two studies conducted in Louisiana’s Kisatchie National Forest investigated longleaf pine physiology in response to spring or fall fire. We hypothesized that after severe scorch, physiological processes linked to growth differed by fire season. Foliage recovered by one growing season after spring or fall fire. Regardless of fire season, factors contributing to foliage recovery included branch persistence and accelerated photosynthesis of residual fascicles. Starch dynamics and its role in post-scorch foliage recovery differed by fire season.
Title: Growth Response of Mature Longleaf Pine to Disturbance at the Harrison Experimental Forest
Authors: John Butnor, Kurt Johnsen, Dana Nelson
Abstract: Young southern pine plantations are very responsive to resource availability, whether from soil nutrition or access to light. When thinning is timed appropriately, trees develop desirable stem quality and their growth rates are maximized. Less is known about the response of mature trees to natural and silvicultural disturbances. Longleaf pine is a long-lived tree that is well suited to extended rotations in the Gulf Coast where natural disturbance from hurricanes periodically occur and thinning for commercial purposes or to create wildlife habitat. We explored the diameter growth of longleaf pine planted in 1961 in the years following disturbances from Hurricane Katrina (2005) and thinning (2011) in at the in Saucier, Mississippi. Winds from Hurricane Katrina destroyed 7% of the longleaf pine, damaging many more, while the thinning was variable, based on existing density. A total of 180 trees were sampled with an increment borer in April 2017 and analyzed to quantify basal area increment (BAI) of both early and late wood. Using BAI normalized to year 2005, we observed that declines of 11 and 13% in 2006-2007, followed by a recovery to 2005 levels by 2011. One year after thinning in 2011, BAI normalized to 2005 increased 50% in 2012, followed by +34%, +8%, +16%, +54% in subsequent years 2013-2016. Clearly the loss of cohort members in 2005 served to reduce stocking levels, but crown damage and loss of foliage likely caused the growth stagnation during next five years. Conversely the thinning was followed by large increases in BAI for two years.
