“…Although conifer-dominated stands are believed to be preferred by marten, xeric-site conifers in particular, are not (Buskirk and Powell 1994). Xeric-site species such as jack pine produce less coarse woody debris (CWD) than do mesic-site species and CWD is considered an important habitat element for martens (Corn and Raphael 1992). The finding that Site Type 8 (black spruce-feathermoss-sphagnum) was not preferred by martens is also contrary to the NE-HSM.…”

In northeastern Ontario, the Forest Ecosystem Classification (NE-FEC) system has been used in a Habitat Suitability Matrix (NE-HSM) for forest wildlife. This paper examines whether American martens (Martes americana) responded significantly to different NE-FEC Site Types, and compares this response with suitability values in the NE-HSM. Use of Site Types by martens deviated significantly from availability; Site Type 5 (black spruce) was preferred and Site Type 7 (hardwood) was avoided. In general, the NE-HSM was consistent with field results; but it was concluded that some adjustments should be made to the suitability values for martens in the Northeastern Ontario Forest Habitat Suitability Matrix. Key words: Forest ecosystem classification, habitat suitability matrix, marten, Martes americana

Down wood and biodiversity — implications to forest practices

2010

Many species require or use down wood (fine and coarse woody debris) as habitat. Where forestry has been practiced for several rotations large proportions of these species are considered threatened. Key attributes determining the suitability of down wood as habitat are decay stage, tree species, and size, specifically diameter. Both quantity and distribution of suitable down wood influence species' presence and abundance. We present a simple framework describing use of down wood based on broad natural history features, derive predictions from the framework, then test these by review and summary of literature. Our focus is terrestrial vertebrates, particularly in the Pacific Northwest. Species other than vertebrates are addressed to ensure that metrics derived for vertebrates also are appropriate for other organisms. Basic metrics are the same, but appropriate values span a larger range among nonvertebrates. Current evidence suggests that the ''extinction debt'' apparent for nonvertebrates is approaching for vertebrates. Predictions derived from underlying natural history hold when tested. From that basis we derive broad guidelines for forest planning and practice, and suggest how regional target values can be derived. Résumé :Plusieurs espèces nécessitent ou utilisent le bois mort (débris ligneux fins ou grossiers) comme habitat. Là où l'on a pratiqué la foresterie au cours de plusieurs rotations, on considère qu'une large proportion de ces espèces deviennent menacées. Les caractéristiques déterminant l'utilité du bois mort comme habitat regroupent l'état de décomposition, les espèces d'arbres et leurs dimensions, surtout le diamètre. Les quantités ainsi que la distribution de bois mort adéquat influencent la présence des espèces et leur abondance. Les auteurs présentent un cadre de travail simple décrivant l'utilisation du bois mort, basé sur des caractéristiques élargies d'histoire naturelle, déduisent des prédictions à partir d'un tel cadre, et les vérifient finalement par une revue et un résumé de la littérature. On met l'accent sur les vertébrés terrestres, particulière-ment de la région du Pacifique nord-ouest. On considère également d'autres espèces que des vertébrés, afin de s'assurer que les chiffres inférés pour les vertébrés sont également appropriés pour d'autres organismes. Les mesures de base restent les mêmes, mais les valeurs pertinentes couvrent un plus large spectre parmi les non-vertébrés. La preuve actuelle suggère que la « dette d'extinction » apparente pour les non-vertébrés approche celle des vertébrés. Les prédictions dérivées de l'histoire naturelle sous-jacente supportent la mise à l'épreuve. Sur cette base, les auteurs déduisent des directives larges pour la planification et la pratique forestière et suggèrent comment on peut en déduire des valeurs cible à l'échelle régio-nale.

Abstract:To better understand human impact on wild animal habitats, we selected three habitat types of Martes zibellina, representing three different successionary stages of their habitats in Huzhong Area, Greater Hing'an Mountain in northeastern China. Employing published literature about behavior ecology, aerial photographs and forest stand maps, we classified the study site into three habitat types, i.e., best-suitable, suitable, and unsuitable. We chose the habitat pattern of the year 1989 in the core zone of Huzhong National Natural Reserve, which is adjacent to Huzhong Area and has similar natural conditions, to represent the primary habitat pattern of Huzhong Area before exploitation. The result showed that, from 1989 to 2000, changes in the best-suitable-habitat was significant, decreasing from 68% to 40%, while suitable habitats decreased from 42% to 17%, whereas unsuitable habitat increased from 21% to 39%. Suitable habitats shrank away from area close to river banks to central forests far away from rivers. Timber harvest proved to be the leading cause of habitat degradation. Our results provide a scientific basis for forest management and animal conservation.
