Data for Moose Population Survey on Western Yukon Flats NWR - Spring, March 2008

We conducted moose surveys in the western Yukon Flats in March 2008.  The population estimate for the 2,269 square mile survey area in the western Yukon Flats (Game Management Unit (GMU) 25D) was 300 moose with a certainty of +/- 20% at the 90% confidence level.  Estimated population density in the high and low density areas was 0.34 and 0.05 moose per square mile, respectively, with an average density estimate of 0.13 moose per square mile.  Calves comprised 11% of the population.  Search times averaged 6.5 minutes per square mile.  We estimated 51% fewer adults, 64% fewer calves, and 53% fewer total moose compared to the spring 2004 survey.  Cows comprise a significant portion of moose harvested throughout the Yukon Flats with up to 26% of total reported harvest in the western Yukon Flats between 2002 and 2007.  Although efforts to increase harvest of bears and wolves were initiated in 2002 we have not documented a positive response in the moose population.  Harvest reports indicate that bear harvest increased between 2002 and 2005 in the western Yukon Flats and decreased in 2006.  Harvest reports indicate wolf harvest increased through 2006 and has since decreased in the western Yukon Flats. The moose population, which has fluctuated at low densities since population estimation monitoring was initiated in 1992, has decreased likely due to mortality rates of cow and calf moose as indicated by harvest reports and low numbers of observed calves in moose surveys.  Decreased bear harvest in the western Yukon Flats may be contributing to decreased calf survival.   In an effort to better manage both prey and predator populations the Refuge and ADFG have implemented, or will be implementing several studies: 1) a wolf study to estimate the winter kill of moose by wolves.  Kill sites will be located, the prey identified, and we will estimate the amount of prey consumed.  2) In spring 2009 and 2010 about 40 black bears will be collared to estimate the total numbers of black bear in a 500 square mile study area centered at Beaver.  3) Lastly, the Refuge will initiate a study of moose habitats in 2009/2010 to estimate the quantity and quality of habitat available for moose forage.  These three studies are being conducted to better understand the relationship of moose and their predators in an effort to develop new strategies to manage both predator and prey populations on the Yukon Flats

Data for Moose Population Survey on Western Yukon Flats NWR - Fall, November 2008

A moose population survey was conducted on the Yukon Flats National Wildlife Refuge in November 2008.  The estimate for the 2,269mi2 survey area in the western Yukon Flats (Game Management Unit [GMU] 25D) was 490 moose (95% confidence interval; 412-569 moose).  Density of moose was 0.22/mi2.  The population was comprised of 251 cows (95% CI; 203-298), 110 calves (83-137), and 127 bulls (100-155).  Search time averaged 6.3 minutes/mi2.  The 2008 estimate of total moose was 15% greater than the November 2006 estimate of 417 (311-524).  This difference was related to numbers of calves, which were 54% greater than November 2006.

Survey Transect Locations for Scrub-Shrub Vegetation and Florida Scrub-Jay Monitoring and Management at Nathaniel P. Reed Hobe Sound National Wildlife Refuge

This reference provides the locations of Scrub-Shrub survey transects associated with vegetation surveys and Florida Scrub-Jay surveys on Hobe Sound National Wildlife Refuge.

These monitoring approaches were identified as a tier 1 priority in the Refuge's interim Inventory and Monitoring Plan.

Hobe Sound National Wildlife Refuge maintains scrub-shrub habitat for the benefit of the Florida Scrub-Jay and the gopher tortoise. A suit of other species benefit from the management of this habitat for those specific species. Management includes mechanic treatment to create open patches and reduce canopy height. Invasive species control is also conducted within the habitat. 

The associated habitat management objective identified in the Phase II decision report is:
Atlantic Coastal Ridge Scrub Objective A.1.1: Over the next 10 years, restore and maintain 70% of Atlantic coastal ridge scrub habitat within suitable conditions for Florida scrub-jay. Suitable conditions include but are not limited to: 

Canopy cover less than 20%; 
Overstory 1 tree > 15ft. per acre;  
10 - 50 % sparse herbaceous cover and open bare sand;  
50 - 80 % mid canopy scrub with a height range of 4 – 7ft;  
A mosaic of multi-age oak understory structure.

Data for Moose Population Survey on Western Yukon Flats NWR - Spring, March 2013

A moose population survey was conducted on the Yukon Flats National Wildlife Refuge in March 2013.  Moose were counted in 101 of 421-5.3 mi2 units, of which 68 were stratified high moose density and 33 low density.  The estimate for the 2,269 mi2 survey area in the western Yukon Flats (Alaska Game Management Unit [GMU] 25D) was 460 total observable moose (95% CI; 345-575).  Density of moose was 0.20/mi2 or 0.08/km2.  The population was comprised of 364 adults (95% CI; 269-458) and 103 calves (63-143).  Search time averaged 6.3 minutes/mi2.  The number of calves was high relative to other spring surveys, but the reasons for this are not known.  There was no detectable trend in spring numbers of total observable moose.  Moose on the Yukon Flats continue to persist at low densities, which has been documented for >50 years.  Continued conservative management of harvest is recommended.

Data for Moose Population Survey on Western Yukon Flats NWR - Fall, November 2010

A moose population survey was conducted on the Yukon Flats National Wildlife Refuge in November 2010.  The estimate for the 2,269mi2 survey area in the western Yukon Flats (Game Management Unit [GMU] 25D) was 440 moose (95% confidence interval; 294-587 moose).  Density of moose was 0.19/mi2.  The population was comprised of 265 cows (95% CI; 170-361), 85 calves (45-125), and 93 bulls (49-137).  Search time averaged 6.5 minutes/mi2.  The 2010 estimate of total moose was 10% less than the November 2008 estimate of 490 (412-569).  Due to fog and winds in mountainous terrain, 7 units went unsampled, 3 of which had good numbers of moose in past surveys.  Accounting for the 7 unsampled units increased the estimate of total moose to approximately 460, using averages of counts in those units since 2004.

Data for Moose Population Survey on Western Yukon Flats NWR - Spring, March 2003

The population estimate for the western Yukon Flats in Game Management Unit (GMU) 25D (2,269 square miles) was 528 moose with a certainty of +1- 25% at the 90% confidence level. Estimated population density in the high and low density areas was 0.63 and 0.09 moose per square mile, respectively, with an average density estimate of 0.23 moose per square mile. Calves comprised 16% of observed calves and 13% of estimated calves in the total population. Search times averaged 6.2 minutes per square mile.

Data for Moose Population Survey on Western Yukon Flats NWR - Fall, November/December 2018

A moose population survey was conducted on the Yukon Flats in November/December 2018.  This was the first fall survey since 2015. Moose were counted in 97 of 421-5.3mi2 units, of which 63 were stratified high moose density and 34 low moose density. The estimate for the 2,269 mi2 survey area in the western Yukon Flats (Alaska Game Management Unit [GMU] 25D) was 1123 total observable moose (95% CI; 895-1351).  Density of moose was 0.49/mi2 or 0.19/km2.  The population was comprised of an estimated 908 adults (95% CI; 698-1118) and 199 calves (148-251). Search time averaged 6.0 minutes/mi2. The estimate of total observable moose increased from the lows of 2004-2010. Improved calf survival may have contributed to the population increase in some years. It is unlikely that public harvest of wolves and bears contributed, as harvest intensity is light. Thus, moose density increased in the presence of lightly harvested wolf and bear populations, suggesting that the dynamics of this low density population may sometimes be more complex than previously thought. Moose numbers can fluctuate naturally within a low density equilibrium over a period of approximately a decade, and this fluctuation can be detected with the current survey method.

Data for Moose Population Survey on Western Yukon Flats NWR - Fall, November 2015

A moose population survey was conducted on the Yukon Flats in November 2015.  This was the first fall survey since 2010 due to a lack of sufficient snow in early winter that caused surveys in 2012-2014 to be cancelled. Moose were counted in 100 of 421-5.3mi2 units, of which 59 were stratified high moose density and 41 low moose density. The estimate for the 2,269 mi2 survey area in the western Yukon Flats (Alaska Game Management Unit [GMU] 25D) was 790 total observable moose (95% CI; 600-980).  Density of moose was 0.35/mi2 or 0.13/km2.  The population was comprised of an estimated 609 adults (95% CI; 460-759) and 191 calves (126256. Search time averaged 6.7 minutes/mi2. The estimate of total observable moose increased from 2010 to 2015. Improved calf survival may have contributed to the population increase in some recent years. It was unlikely that public harvest of wolves and bears contributed, as harvest intensity was light. Thus, moose density increased in the presence of lightly harvested wolf and bear populations, suggesting that the dynamics of this low density population may sometimes be more complex than previously thought.

Invasive Plant Inventory and Early Detection Prioritization Tool for Stewart B. McKinney NWR

In 2010-2013, the U. S. Fish and Wildlife Service (USFWS) partnered with Utah State University to conduct invasive plant prioritization workshops and inventories on selected National Wildlife Refuges across the United States.  The purpose of these workshops and subsequent inventories was to inform and improve the process of planning and implementing invasive plant inventories or early detection.  These workshops highlighted the need for an objective, transparent and documented process for deciding which invasive plant species should be a focus of inventory or early detection (and ultimately management) and where. A result of this partnership is the Invasive Plant Inventory and Early Detection Prioritization Tool (IPIEDT) and associated user's guide.  The tool is a Microsoft Access database (2010 or later) that utilizes site-specific knowledge and harnesses existing invasive plant information (invasive species risk rankings) to identify priority species and areas for inventory or early detection. The tool produces a ranked list of areas and invasive plant species to consider for inventory or early detection. Once the location and abundance of priority invasive plants are understood, this information can be used to decide what specific management strategies should be employed and where. Interior 1 Regional and Refuge staff used the database developed by Utah State and the Pacific Southwest Region to prioritize invasives species at Stewart B. McKinney. The attached products are the result of that prioritization.

Juvenile Atlantic Sturgeon Monitoring in the Hudson River, NY

This dataset contains catch data for juvenile Atlantic Sturgeon in the Hudson River from 2003 - 2005.  This project was funded by the NY State Department of Environmental Conservation (NYSDEC) through a reimbursable agreement with the Northeast Fishery Center with the objective of developing a juvenile Atlantic Sturgeon monitoring program which NYSDEC could then continue into the future.  A stratified random sampling design was implemented in Newburgh and Haverstraw Bays of the Hudson River with strata consisting of combinations of depth and substrate type.  Juvenile Atlantic Sturgeon were captured with gillnets in the spring (March - April) and fall (October - November). The results of this work recommended locations, time of year, and sample sizes for continued monitoring of the juvenile Atlantic Sturgeon into the future.

Oregon Coast Wide Tufted Puffin Colony Survey 2021 - Maps

The Tufted Puffin (Fratercula cirrhata) is a medium-large pelagic seabird and member of the Auk family. The distribution of the Tufted Puffin is widespread in the North Pacific Ocean and populations have generally declined throughout the southern portion of their range from British Columbia to northern California. The U.S. Fish and Wildlife Service (USFWS) conducted a burrow-nesting seabird survey of the Oregon coast in 2008 and documented an order of magnitude decline in the puffin population since the previous survey in 1988. During summer 2021, USFWS conducted an Oregon coast wide survey of the Tufted Puffin during the chick rearing period from July 14 – August 25 to assess and document the current breeding population. A total of 62 historical colonies were surveyed, 16 active colonies were documented, and no new colonies were detected. The current Tufted Puffin estimated breeding population of Oregon is 519 individuals. The breeding population remains low but stable compared to previous coastwide surveys.

Data for moose population survey of the western Yukon Flats – Spring, March 2023

A moose population survey was conducted on the Yukon Flats National Wildlife Refuge in March 2023.  Moose were counted in 102 of 421-5.3 mi2 units, of which 67 were stratified high moose density and 35 low density. The estimate for the 2,269 mi2 survey area in the western Yukon Flats (Alaska Game Management Unit [GMU] 25D) was 675 total observable moose (95% CI; 509-841).  Density of moose was 0.30/mi2 or 0.11/km2.  The population was comprised of an estimated 589 adults (95% CI; 441-736) and 88 calves (49-128).  Search time averaged 5.8 minutes/mi2. Spring moose numbers were above the long-term average (average 554, range 300735). The proportion of calves was intermediate relative to past spring surveys. Moose on the western Yukon Flats continue to persist at low densities, which has been documented for >60 years.
