The methodology used for this migration analysis allowed for the mapping of winter ranges and the identification of migration corridors. They were developed from 44 migration sequences collected from a sample size of 14 animals comprising GPS locations collected every 3-13 hours. Thirty-six migration sequences from 9 deer, with an average migration time of 19.53 days and an average migration distance of 87.57 km, were used from the 2017-2020 dataset. 14-17 months (nearly 1.5 million deer locations recorded since 2005) Currently 108 deer "on the air" (94 does, 14 bucks) Findings to Date Migration Timing Average fall migration: Oct 8 - Nov 17 Average spring migration: May 9 - Jun 24 Mortality Factors (Fig 2) Annual Survival Estimates (Table 1) By working closely with their state agency partners, non-governmental organizations can play an important role to act as a force multiplier to help with project funds, prioritization, volunteer labor, and advocacy when things get controversial. When caribou migrate, they also make it less likely that young Caribou calves wont be eaten by predators. Winter range is visualized as the 50th percentile contour of the winter range utilization distribution. The migration routes and range locations of deer are passed down through families from generation to generation. Mule deer (11 adult females) from the Downieville-Nevada City herd were captured and equipped with Lotek Iridium Track MGPS collars, transmitting data from 2018-2021. The most hazardous portion of the Round Valley herd's migration route occurs near the community of Swall Meadows by the top of the Sherwin Grade. A large wildlife crossing structure was installed by California Department of Transportation and CDFW on Highway 89 to mitigate some of the impacts from vehicle collisions for this herd. This means they stopover in areas with good food until being driven down by snow storms. 2009) were constructed with GPS collar data from 5 migrating deer, including 16 migration sequences, location, date, time, and average location error as inputs in Migration Mapper. Stopovers were calculated as the top 10 percent of the population level utilization distribution during migrations and can be interpreted as high use areas. If not now, when? Our actions today for the conservation of these corridors will be heralded by future generations just as some of the early conservation efforts are celebrated today. This collar project was not specifically designed to pinpoint precise migration routes or winter range designations, hence the low sample size. Montana published their first maps of big game movements in the 1960s and these guided land purchases and hunt season structures at the time. To many people, a mule deer is simply a mule deer. The Geospatial Data. Some areas do not lend themselves well to being able to use optics to spot deer, so many hunters will utilize an Eastern tactic of sitting up in a treestand and waiting for the deer to come to them. Corridors and stopovers were prioritized based on the number of animals moving through a particular area. The overall population of deer will be relatively low when compared to other areas, and the animals will be scattered around solid food and water sources. Much research has been done on habitat fragmentation to show the genetic and numerical effects on wildlife populations. (2010), the GPS data were filtered prior to analysis to remove locations which were: i) further from either the previous point or subsequent point than an individual deer is able to travel in the elapsed time, ii) forming spikes in the movement trajectory based on outgoing and incoming speeds and turning angles sharper than a predefined threshold , or iii) fixed in 2D space and visually assessed as a bad fix by the analyst.The methodology used for this migration analysis allowed for the mapping of winter ranges and the identification and prioritization of migration corridors in a single deer population. 1785 East 1450 South As weve seen here, many types of deer migrate every year. Summer range habitat is more abundant and nutritious in most places, but the availability of winter range and migration corridors is limited and frequently in conflict with human land uses.
