The Distribution and Reproductive Success of the Western Snowy Plover along the Oregon Coast - 2009

From 3 April – 23 September 2009 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius alexandrinus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, New River, and Floras Lake. Our objectives for the Oregon coastal population in 2009 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue selective use of mini-exclosures (MEs) to protect nests from predators and evaluate whether exclosure use can be reduced, 4) determine nest success, 5) determine fledgling success, 6) monitor brood movements, 7) collect general observational data about predators, and 8) evaluate the effectiveness of predator management. We observed an estimated 199-206 adult Snowy Plovers; a minimum of 149-150 individuals was known to have nested. The adult plover population was the highest estimate recorded since monitoring began in 1990, and we found 236 nests in 2009. Overall Mayfield nest success was 23%. Exclosed nests (n = 34) had a 76% success rate, and unexclosed nests (n = 202) had a 25% success rate. Nest failures were attributed to unknown depredation (29%), rodent depredation (21%), unknown cause (17%), oneegg nests (12%), corvid depredation (8%), abandonment (7%), wave overwash (2%), infertility (1%), wind (1%), canine depredation (1%), and raccoon depredation (1%). We monitored 88 broods, including eight from unknown nests, and documented a minimum of 106 fledglings. Overall brood success was 73%, fledgling success was 50%, and 1.33 fledglings per male were produced. Continued predator management, habitat improvement and maintenance, and management of recreational activities at all sites are recommended to achieve recovery goals

The Distribution and Reproductive Success of the Western Snowy Plover along the Oregon Coast - 2012

From 5 April – 21 September 2012 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius nivosus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Snowy Plover Management Area, New River HRA and adjacent lands, and Floras Lake. Our objectives for the Oregon coastal population in 2012 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) determine nest success, 4) use mini-exclosures (MEs) to protect nests from predators as needed, 5) determine fledging success, 6) monitor brood movements, 7) collect general observational data about predators, and 8) evaluate the effectiveness of predator management. We observed an estimated 290-91 adult Snowy Plovers; a minimum of 231-238 individuals was known to have nested. The adult plover population was the highest estimate recorded since monitoring began in 1990. We monitored 314 nests in 2012; the highest number of nests since monitoring began in 1990. Overall apparent nest success was 45%. Exclosed nests (n = 22) had an 82% apparent nest success rate, and unexclosed nests (n = 289) had a 42% apparent nest success rate. Nest failures were attributed to unknown depredation, unknown cause, corvid depredation, abandonment, one egg nests, wind/weather, mammalian depredation, overwashing, adult plover depredation, and infertility. We monitored 154 broods, including 11 from unknown nests, and documented a minimum of 173 fledglings. Overall brood success was 70%, fledging success was 43%, and 1.37 fledglings per male were produced. Continued predator management, habitat improvement and maintenance, and management of recreational activities at all sites are recommended to achieve recovery goals

We monitored 346 nests in 2014. Overall apparent nest success was 60%. Nest failures were attributed to unknown depredation, unknown cause, mammalian depredation, abandonment, wind/weather, one-egg nests, avian depredation, overwashed, infertility, and corvid depredation. We monitored 221 broods, including 12 from unknown nests, and documented a minimum of 272 fledglings. Overall brood success was 77%, fledging success was 48%, and 1.68 fledglings per male were produced

Increasing low-carbon energy in Scottish agriculture through a whole systems approach

The Climate Change Plan update sets out targets to reduce emissions from the agriculture sector. Carbon dioxide emissions associated with stationary combustion sources and off-road machinery use in agriculture contribute significantly to agricultural emissions and have increased between 2020 and 2021. The impact of agriculture’s energy use can be difficult to account for, with emissions being captured within grouped sectors (electricity, gas and other) of the GHG inventory. This report examines the energy use and associated emissions baseline on farms and crofts in Scotland, and explores the potential for efficiency measures and new, low-carbon technologies to support energy emissions reductions in the longer term
