Airborne laser scanning (ALS) is a remote sensing technology known for its applicability in natural resources management. By quantifying the three-dimensional structure of vegetation and underlying terrain using technology, ALS has been used extensively enhancing geospatial knowledge fields forestry ecology. Structural descriptions provide means estimating range ecologically pertinent attributes, such as height, volume, above-ground biomass. The efficient processing large, often technically...
Implementation of wildfire- and climate-adaptation strategies in seasonally dry forests western North America is impeded by numerous constraints uncertainties. After more than a century resource land use change, some question the need for proactive management, particularly given novel social, ecological, climatic conditions. To address this question, we first provide framework assessing changes landscape conditions fire regimes. Using framework, then evaluate evidence change contemporary...
Abstract Historical reference conditions have provided empirical benchmarks for guiding ecological restoration but the relevance of historical has been questioned in this era rapid global change. Trait‐based ecology offers an alternative approach setting objectives. If we understand which phenotypic traits confer high survival a given environment, then can restore assemblages species with favorable trait combinations to reduce mortality risk, achieve functional outcomes, and enhance success....
Applications of lidar in ecosystem conservation and management continue to expand as technology has rapidly evolved. An accounting relative accuracy errors among platforms within a range forest types structural configurations was needed. Within ponderosa pine northern Arizona, we compare vegetation attributes at the tree-, plot-, stand-scales derived from three platforms: fixed-wing airborne (ALS), fixed-location terrestrial (TLS), hand-held mobile laser scanning (MLS). We present...
Abstract Questions: How did an initial tree harvest in 1894 influence the spatial and temporal patterns of Pinus ponderosa recruitment? do these compare to our understanding P. stand dynamics prior Euro‐American settlement? might pattern information, particularly with respect patch characteristics, inform current restoration management practices? Location: A 2.59‐ha permanent sample plot Fort Valley Experimental Forest, Flagstaff, Arizona. The was selectively harvested measured 1909 2002....
Post-fire predictions of forest recovery under future climate change and management actions are necessary for managers to make decisions about treatments. We applied the Climate-Forest Vegetation Simulator (Climate-FVS), a new version widely used model, compare alternative scenarios in severely burned multispecies Arizona, USA. The incorporation seven combinations General Circulation Models (GCM) emissions altered long-term (100 years) condition compared No Climate Change (NCC) scenario,...
Climate warming, land use change, and altered fire regimes are driving ecological transformations that can have critical effects on Earth's biota. Fire refugia-locations burned less frequently or severely than their surroundings-may act as sites of relative stability during this period rapid change by being resistant to supporting post-fire recovery in adjacent areas. Because value forest ecosystem persistence, there is an urgent need anticipate where refugia most likely be found they align...
Multiscale spatial patterns of forest reference conditions offer insight on how historical and environmental processes have influenced stand dynamics. Yet, information is often either unavailable or partial, because many studies provide nonspatial condition information, whereas others only report the local (i.e. observed at plot extent) arrangement trees. However, knowledge multiscaled patterns, including stand‐, among‐patch‐, within‐patch‐level needed to ensure that management strategies...
Summary Historical reference conditions have long been used to guide the restoration of degraded ecosystems. However, a rapidly changing climate and altered disturbance regimes are calling into question usefulness this approach. As consequence, goals increasingly focused on creating communities that resilient novel environmental stressors emphasis is being placed defining functional targets through use plant traits. While changes in forest structure composition received much attention,...
