Snag density varies with intensity of timber harvest and human access

Many species of vertebrates depend on snags (standing dead trees) for persistence, and limited research suggests that snag density is lower in areas of intensive timber harvest and increased human access. While intensive timber harvest is one source of potential snag loss, ease of human access to forest stands may also facilitate loss via firewood cutting of snags. Accordingly, we hypothesized that density of snags (number of snags/ha) would decline in forest stands with increasing intensity of timber harvest and increasing ease of human access. We tested our hypothesis by sampling stands under varying levels of timber harvest and access on National Forest land in the northwestern United States. Stands with no history of timber harvest had 3 times the density of snags as stands selectively harvested, and 19 times the density as stands having undergone complete harvest. Stands not adjacent to roads had almost 3 times the density of snags as stands adjacent to roads. Unharvested stands adjacent to non-federal lands and closer to towns had lower snag density, as did stands with flat terrain in relation to nearest road. Our findings demonstrate that timber harvest and human access can have substantial effects on snag density. Meeting snag objectives for wildlife will require careful planning and effective mitigations as part of management of timber harvest and human access.

Urban greenspace access,uses, and values: A case study of user perceptions in metropolitan ravine parks

Urban greenspaces provide critical ecosystem services to urban area residents. While urban greenspaces provide a range of ecosystem services, cultural ecosystem services may be the most prominent to residents. Cultural ecosystem services provide benefits through educational, recreational, social, and spiritual opportunities. More knowledge is required about greenspace users’ perspectives of their local greenspaces, which will enrich park planners’ knowledge of the preferences, concerns, and potential points of conflict that greenspace users experience. To help increase this knowledge, we conducted a survey with closed and open-ended questions and supported it with a park audit and photographic evidence. As a case study, data were collected in six ravine parks in the City of Toronto, Canada. Ravine parks were of particular interest as they are a unique form of socio-ecological greenspace that have varied management goals which on occasion may differ from some user preferences and values. Quantitative data were analyzed with analysis of variance and chi-square tests of independence, and qualitative data were analyzed with conventional qualitative content analysis. Our results highlight that current ravine park users vary widely in their characteristics and the values they pursue through their park access. While the range of ravine park types accommodates some of this variability, there is also conflict between ravine park users with different values and expectations. We are offering a series of recommendations addressing these findings and hope that insights from this deep and rich case study will be of use to other forested, urban greenspaces under similar conditions.
