What these salamanders could tell us about the health of Nova Scotian forests The eastern red-backed salamander may hold the key to better understanding the health of old hemlock forests in southwestern Nova Scotia. Researchers are looking at salamander populations and behaviour to study the impacts of an invasive bug and the insecticides we use to fight it. https://www.cbc.ca/news/canada/nova-scotia/salamander-insecticide-hwa-impacts-9.7302030?cmp=rss

Most of my afternoon today was spent in #QGIS with one of my Masters students Dee Patel. We're preparing my long-term bird monitoring data around Christchurch, NZ, for analysis. Today we gridded up my four standard bike transects into 1 km sections, surrounded by approximately 1 km square polygons. Dee's particularly interested in how the conversion of farmland to urban housing affects birds. Next Dee will be doing some clever analysis of my distance sampled bird counts to estimate the density of each bird species in each grid cell in each month over the past 12–23 years (depending on the route). She'll then compare those densities with land use changes from the NZ land cover database. It's going to be interesting to see what patterns emerge. #EcologicalMonitoring #birds #nz #ecology #LincolnUniversityNZ

This week was the 18th birthday of fortnightly run route through southwestern Ōtautahi-Christchurch, NZ. This is my 10.1 km route where I've been counting and mapping all the birds and butterflies and assorted other species. I started the route on 9 July 2008, while on parental leave, pushing my baby daughter around in a buggy during her afternoon nap. I wanted her to be able to know how the city's nature changes over her lifetime. I've been doing it ever since (and have added three other routes to cover other parts of the city). In celebration of the route's 18th birthday, here are all the korimako (NZ bellbirds) I've seen and heard. Korimako have been a huge success story for the city. The native forest regeneration and pest control happening in the city's Port Hills have led to booming numbers of korimako, and the native tree plantings in the city have been attracting birds out from the hills. As my run route has shown, within the city the korimako are mostly in areas of native tree plantings and in gardens with mature bird nectar plants (especially kōwhai, banksia, eucalyptus, and harakeke). Korimako are still largely absent from the areas of housing that don't have any of these. (We still need many more native trees in the city if we want more native birds.) #wildcounts #EcologicalMonitoring #birds #Christchurch #Ōtautahi #NZ #nature #ecology

Here's an animated movie of the accumulating korimako observations over the past 18 years along my fortnightly 10.1 km run route in Ōtautahi-Christchurch, NZ. https://flic.kr/p/2soCFTA #wildcounts #EcologicalMonitoring #birds #Christchurch #Ōtautahi #NZ #Flickr #animation #map #qgis #bellbird
