Traditionally, ecosystem mapping is undertaken through a combination of fieldwork and aerial photography interpretation. These methods, however, are time-consuming, prone to subjectivity, and difficult to update. Light Detection and Ranging (LiDAR) is an advanced remote sensing technology that has rapidly increased in application in the past decade and has the potential to significantly increase and refine information content of ecosystem mapping, especially in the vertical dimension. LiDAR technology is therefore well-suited to providing detailed information on topography and vegetation structure and has considerable potential to be used for ecosystem classification and mapping. In this article, the potential to use LiDAR data to advance ecosystem mapping is examined. The current state of the science for using LiDAR data to classify and map key ecosystem attributes within an existing ecosystem mapping scheme is discussed by focusing on British Columbia Terrestrial Ecosystem Mapping and its associated Predictive Ecosystem Mapping. The article concludes by summarizing which components of ecosystem mapping and classification are best suited to the application of LiDAR data, followed by a discussion of the feasibility and future directions for mapping ecosystems with LiDAR technology.","PeriodicalId":129797,"journal":{"name":"Journal of Ecosystems and Management","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127207583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigagtes the impact of mountain pine beetle in these young pine stands. In 2005 and 2006, 24 plots were established throughout the mountain pine beetle-affected area of British Columbia. Cumulative mortality reached 83% in some plots. Secondary bark beetles and other pests contributed to overall stand mortality and decline but to a far lesser degree than mountain pine beetle. Stem deterioration and falldown was very rapid and severe in young stands following attack. Over 70% of attacked trees in the Sub-Boreal Spruce ecosystem were severely deteriorated, or had fallen less than 5 years after attack. The largest pines in young stands were attacked first, and brood production and emergence in these trees was more successful than in smaller, younger cohorts. Many attached stands had received silvicultural treatments. Once the outbreak in adjacent mature stands had subsided, very little new attack occurred in these young stands. Brood production was successful, albeit lower in young trees than in mature trees.","PeriodicalId":129797,"journal":{"name":"Journal of Ecosystems and Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130760872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among 30, 16-ha live-trapping grids, estimated mean abundance of both species increased non-linearly with remaining basal area of live overstorey (live trees ≥ 7.5 cm diameter at 1.3 m height). A weak (most likely positive but possibly negative) additional response of flying squirrels to dead overstorey (on average 1 m2/ha dead ≈ +0.11 m2/ha live basal area) was evident. The basal area of live spruce-fir (Picea spp., Abies spp.) overstorey, understorey tree density, and tree diameter covariates did not have substantive additional effects on estimated squirrel abundance. Whereas survey year affected overall abundance, it did not change the relationship with habitat attributes. The results suggest that dead lodgepole pine (Pinus contorta) has low habitat value for arboreal squirrels and thus is of lower impact on squirrels if salvage-harvested; however, retention or re-growth of sufficient live overstorey is necessary to maintain or recover squirrel abundance. The basal area oflive overstorey appears a simple yet useful management metric for prioritizing habitatvalue, at least as indicated by relative abundance for squirrels in beetle-affected forests.","PeriodicalId":129797,"journal":{"name":"Journal of Ecosystems and Management","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122700992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the impact of cattle ranching on these emissions in British Columbia in order to determine the overall carbon footprint. The grazing activity within the Lac du Bois grasslands of British Columbia was examined, with emphasis on identifying point sources and removals of greenhouse gas emissions from cattle ranching. Enteric methane emissions were empirically measured at two elevation gradients in the spring and fall of 2010. Cattle emitted on average 370 L CH4 per day; these measurements on native grasslands are comparable to work on tame pastures. A life cycle analysis was conducted with a validated HOLOS model based on empirical measurements. The following grassland improvement strategies were evaluated: reducing stocking density; and reseeding/interseeding grass and legumes with and without synthetic fertilizer additions. Reseeding was the most effective at reducing the carbon footprint of cattle ranching on the Lac du Bois grasslands. Reseeding initiatives could theoretically result in soil carbon sequestration rates of 2.12 Mg CO2 equivalent per hectare. A combination of reductions and removals should be implemented in the future to reduce the overall carbon footprint of cattle ranching in British Columbia.","PeriodicalId":129797,"journal":{"name":"Journal of Ecosystems and Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129107039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
