Community Forests

The effects of climate change in many regions are expected to be significant, and likely to have a detrimental effect on the health of forests and the communities that often depend on those forests. At the same time climate change presents a challenge as it requires changes in both forest management, and the institutions and policies developed that govern forest management. In this paper, we report on a study assessing how Community Forests Organizations (CFOs) in British Columbia (BC), which were developed to manage forests according to the needs and desires of local communities and First Nations, are approaching climate change and whether or not they are responding to, or preparing for, its impacts. There are practical steps that CFOs can take to improve their ability to cope with future conditions such as planting a wider variety of species, practising different silvicultural techniques and increasing monitoring and observation of the forest. This paper gives an overview of what current capabilities exist in CFOs and suggests potential areas for targeted development.

Changes in forest tenure policies may create insecure investment environments for tenure holders, which can result in misallocations of investment capital. A methodology is developed to measure tenure holders' perceived security in their tenure arrangements. The methodology is applied to three types of tenures in British Columbia. Results indicate that tenure holders perceive Tree Farm Licences and Timber Lands as insecure and Taxation Tree Farms as secure.

Abstract. Wirabuana PYAP, Setiahadi R, Sadono R, Lukito M, Martono DS, Matatula J. 2020. Allometric equations for estimating biomass of community forest tree species in Madiun, Indonesia. Biodiversitas 21: 4291-4300. The capability of community forests for offsetting carbon emissions highly depends on their biomass production. Unfortunately, the measurement of tree biomass in community forests using a destructive method is expensive and time-consuming. It is also almost impossible to conduct this method for all trees in the observation area. Therefore, the development of allometric equations is essential to support tree biomass estimation in community forests. This study was designed to construct specific models for predicting individual tree biomass in community forests, located in Madiun, Indonesia. We destructively sampled approximately 120 trees from four different species (30 trees for each species), i.e., Falcataria moluccana, Melia azedarach, Swietenia macrophylla, and Tectona grandis. For every tree sample, the measurement of biomass was conducted in each tree’s component, namely roots, stem, branches, and leaves. The allometric equations were developed with regression analysis using predictor variables, like diameter at breast height (D), squared diameter at breast height combined with tree height (D2H), as well as D and H separately. Results found that for four species, the mean biomass in the stem was 50.3%, followed by branches 25.4%, roots 15.9%, and leaves 8.3%. The best equation for estimating biomass in every component and total of four species was different. However, our study showed that the equation lnŶ = -3.037 + 1.430 lnD + 1.684 was reliable to estimate total individual tree biomass of four species in the surveyed area since this model had accuracy of 90.8%. Referring to these findings, we recommended the utilization of an allometric equation as an alternative method for facilitating more efficient biomass measurement in the community forests.

In 1996, a windbreak planting of Abies concolor (Gordon & Glend.) Lindl. ex Hildebr. and A. lasiocarpa (Hook.) Nutt. on a Christmas tree farm in Lamoille County, VT, incurred tip blight caused by a Delphinella sp. Although only scattered new shoots of the intermixed A. concolor and nearby A. balsamea (L.) Mill. were killed, more than 75% of the new shoots in the lower 1.8 m of the crowns of A. lasiocarpa were killed. This posed the question, whether the pathogen was the native D. balsameae (A. M. Waterman) E. Müller in E. Müller & Arx or whether the western species, D. abietis (Rostr.) E. Müller in E. Müller had been introduced. Dead 1996 shoots were collected from all species on 15 July. Most ascomata were immature. However, occasional ascomata bore well-developed bitunicate asci with hyaline, uniseptate ascospores averaging 40 × 9 μm, confirming the pathogen was D. balsameae (1). Funk reported this pathogen on A. lasiocarpa in British Columbia without documentation; this is the first record of it attacking this species in eastern North Amer-ica. Although the seed source was unknown, the extreme susceptibility of A. lasiocarpa in comparison to other Abies spp. in the area suggests that caution should be used in planting this species in the Northeast.

Conservation Plans

Over the last decade, forest tree breeders have become aware of the need for gene conservation, but have struggled with methods that would meaningfully integrate breeding and conservation populations. Gene Namkoong has provided the most guidance in this area by defining the role of in- and ex-situ populations in forest tree gene resource management and, particularly, the need for this to be dynamic in time and space. However, once conservation plans for individual species in British Columbia were considered, it became clear that more quantitative structure was needed to provide a framework for attaining practical management objectives. This paper attempts to provide such a framework and show how breeding and conservation populations can be integrated into a continuum of genetic resources. First, capturing only one copy of an allele is likely not satisfactory to meet conservation objectives, and sampling targets should be set higher (e.g., 20) so as to avoid potential problems of inbreeding at later stages in the program. Second, there seems to be a large problem with conserving very low frequency alleles that are recessive, but this occurs in nature as well. Third, in situ populations should be large enough and in a state to persist on their own over several generations, so the more recent effective population size numbers proposed by Lynch (1996) (i.e., ~1000) need to be considered. Fourth, while breeding populations of moderate size (~80) will contain adequate amounts of quantitative genetic variation, they will also contain 20 copies of dominant alleles at frequencies of ~0.20 or higher. Fifth, maintaining and rejuvenating strategic ex-situ test populations now seems to be the only way to conserve low- to mid-frequency alleles that will (i) be reduced in progressive breeding populations by drift and, (ii) over time, not be in desirable genetic backgrounds in in situ populations. Sixth, any reliance on locating mutants in production populations seems generally remote and cannot be relied upon except in a very few situations, although mutation will be important in breeding and in reserves in situ.
