Mexico´s 4,111 islands host 8.3% of the country’s plants and land vertebrates. They harbour one in three seabirds worldwide, placing Mexico as the third most diverse country. Invasive mammals have had a big toll on Mexico’s biodiversity, with 17 out of 21 confi rmed vertebrate extinctions occurring on islands. The Mexican conservation organisation Grupo de Ecología y Conservación de Islas (GECI), in collaboration with Mexico’s federal government, and a wide network of national and international donors, has been leading the National Programme for Island Restoration that has grown in scope. The fi rst eradications on small islands fostered trust amongst partners, setting the foundations for complex eradications on bigger islands requiring innovation, capacity development, and research. Island biosecurity is now a priority for long-term tangible results. This programme evolved to be truly comprehensive, including post-eradication restoration to strengthen island resilience, and the social construction of a cultural approach integrating interests from conservation and local fi shing communities. Results to date include: (1) eradication of 58 populations of invasive mammals from 37 islands; (2) publication of both a National Island and Invasive Species Strategy, identifying conservation priorities; (3) ongoing active restoration of seabird colonies and native plant communities; (4) original applied research and ad hoc infrastructure and equipment to support restoration; (5) legal protection of all Mexican islands; (6) assessing the eff ects of climate change on islands’ biodiversity and human populations; and (7) formation of in-house specialists through postgraduate studies in collaboration with research institutes and universities from Mexico and elsewhere. As for the future, we foresee two priorities: (1) remove invasive mammals from all Mexican islands by 2030; and (2) promote the creation of an “International Islands Institute” that could operate under a wide international collaboration and interdisciplinary approach.

The Pacifi c invasives partnership – a model for regional collaboration on invasive alien species The Pacifi c invasives partnership – a model for regional collaboration on invasive alien species P.C.

Cowan U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Washington DC, USA. <[email protected]> Invasive Alien Species (IAS) are a fundamental challenge facing Pacifi c Island Countries and Territories (PICTS), impacting economies, habitats, food security, biodiversity, livelihoods and quality of life. These negative and substantial impacts are being acknowledged by PICTs leaders as well as on the international stage. As the inter-relatedness of IAS and other fundamental challenges such as climate resilience, oceans and sustainability are understood and acknowledged, strategies to integrate IAS and biosecurity concepts into international eff orts will require invasive species expertise and guidance. The Pacifi c Invasives Partnership (PIP) is a group created by the Pacifi c Roundtable for the Conservation of Nature that has evolved into a broad advocate for IAS outreach and an incubator for collaborative IAS eff orts in the Pacifi c. PIP comprises volunteer IAS experts from regional, national, NGO and international groups that work in two or more PICTS and want to advance IAS issues. By taking a “rising tide fl oats all boats” approach, PIP members work to raise the profi le and understanding of IAS as a fundamental, underpinning issue to PICT economies, environments and future sustainability. PIP successes over the past fi ve years include reports and briefi ng materials prepared for the Pacifi c Islands Forum Leaders meeting, provision of advice and assistance for Pacifi c invasive species Global Environment Facility projects, leading and supporting regional and sub-regional projects on regional biosecurity, invasive ant and rodent eradication and prevention, and the successful raising of the IAS profi le at various international fora. PIP is a successful model of regional collaboration on invasive alien species and could be used as a model for similar eff orts in other island regions of the world. P.C. Andreozzi, R. Griffi ths, D.

A review of monitoring of biodiversity responses to island invasive species eradications A review of monitoring of biodiversity responses to island invasive J. Bird, J. Shaw, R. Alderman and R. Fuller species eradications J. Bird, J. Shaw, R. Alderman and R. Fuller Centre for Biodiversity & Conservation Science, University of Queensland, School of Biological Sciences, University of Queensland, St Lucia, Queensland 4072 Australia. <[email protected]> A recent review examined the benefi ts from invasive species eradications on islands worldwide. While the review concluded that island eradications are overwhelmingly benefi cial for native biodiversity, a response to eradication was only demonstrated for 22 of the 532 islands treated. While many studies advocate monitoring, there appears to be a gap, either between eradication eff ort and monitoring eff ort, or between monitoring and analysing/reporting responses. We focussed on regions of the Pacifi c, Australia and the Caribbean to document the level of monitoring on islands where eradications have taken place. We collated published and unpublished literature and spoke to key practitioners in the region to investigate targets for monitoring, duration and frequency of monitoring, and the ability of implemented monitoring work to detect responses. We also investigated drivers of monitoring such as type of funder or implementing organisation behind the eradication operation. The study’s fi ndings highlight apparent biases in monitoring eff ort, they provide a benchmark of current monitoring eff ort, and open the debate on when and where monitoring should be undertaken and how best to develop optimal monitoring strategies.

Havery Species and Habitats, Royal Society for the Protection of Birds, RSPB, Headquarters, the Lodge, Sandy, Bedfordshire SG19 2DL, UK. <[email protected]> Lundy, a 450 ha island situated 19 km off the Devon coast in the UK’s Bristol Channel, is internationally important for its marine life and its waters were established as the UK’s fi rst Marine Nature Reserve in 1971. Lundy is home to eleven seabird species, including Manx shearwater (Puffi nus puffi nus), for which the UK has a global responsibility and Atlantic puffi n (Fratercula arctica), a globally threatened species. Steep declines in Lundy’s seabird populations, with puffi ns nearing extinction and low numbers of Manx shearwaters, led to the establishment of the Seabird Recovery Project in 2001. The project aimed to improve the conditions for these burrow-nesting seabirds through the eradication of brown and black rats. From 2002–2004 a ground-based operation was undertaken, and in 2006 Lundy was offi cially declared rat-free. The seabird populations of Lundy have been well studied with detailed regular data spanning the last 35 years. Over the last decade, as a result of rat removal, seabird numbers on the island have doubled and storm petrels have colonised. By 2013, the breeding population of Manx shearwaters increased more than ten-fold to an estimated 3,451 pairs. In 2004, the puffi n population on Lundy fell to an all-time low with only fi ve individuals, but in 2013, more than 80 individuals were recorded. Here we discuss the observed seabird responses to the eradication and present the most recent results of the monitoring surveys from 2017. These impressive results highlight the importance of and need for eff ective biosecurity to reduce the risk of re-incursion of rats.

  • 2017 City of York Biodiversity Action Plan
    CITY OF YORK Local Biodiversity Action Plan 2017 City of York Local Biodiversity Action Plan - Executive Summary What is biodiversity and why is it important? Biodiversity is the variety of all species of plant and animal life on earth, and the places in which they live. Biodiversity has its own intrinsic value but is also provides us with a wide range of essential goods and services such as such as food, fresh water and clean air, natural flood and climate regulation and pollination of crops, but also less obvious services such as benefits to our health and wellbeing and providing a sense of place. We are experiencing global declines in biodiversity, and the goods and services which it provides are consistently undervalued. Efforts to protect and enhance biodiversity need to be significantly increased. The Biodiversity of the City of York The City of York area is a special place not only for its history, buildings and archaeology but also for its wildlife. York Minister is an 800 year old jewel in the historical crown of the city, but we also have our natural gems as well. York supports species and habitats which are of national, regional and local conservation importance including the endangered Tansy Beetle which until 2014 was known only to occur along stretches of the River Ouse around York and Selby; ancient flood meadows of which c.9-10% of the national resource occurs in York; populations of Otters and Water Voles on the River Ouse, River Foss and their tributaries; the country’s most northerly example of extensive lowland heath at Strensall Common; and internationally important populations of wetland birds in the Lower Derwent Valley.

"It's a tribute in a lot of ways," Rocker (nee Leon Drucker) tells Billboard. "It's a song I wrote over the last couple of months. I was thinking about my career with 40 years of Stray Cats and all of that and thinking about the upright bass, which is what started this thing. It takes me back to the opening line of the song -- which is "Took me 'round the world and I changed my name/found a little fortune, found a little fame/Doin' the dog house shuffle" -- which is right out of my story. Dog House is what they call the upright bass, so it's a tribute to the bass itself and a lot of the players that I came up listening to." Some of those players -- including Elvis Presley's Bill Black, Willie Dixon, Fred Maddox, the Tennessee Three's Marshall Grant, Carl Perkins' brother Clayton and Al Rex of Bill Haley & His Comets -- are featured in the "Dog House Shuffle" video, along with cartoon animations and studio footage of Rocker and his band recording the track.

COMPARATfVE SEASONALITY AND DIETS OF GERMAN (Vespula germanica) AND COMMON (V. rnlgaris) WASP COLONIES IN MANA WA TU, NEW ZEALAND A thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University Peter Lance Godfrey 1995 FRONTISPIECE: overwintering German nest found near Bulls on March 2 1994. Extracted on March 24 1994, the nest contained an 570,500 worker/male cells and 32,500 queen cells (R. J. Harris, pers. comm.). ABSTRACT German wasp ( Vespu!a gemw11ica) and common wasp ( V. l'lllgaris) colonies were studied in urban and rural habitats in Manawatu, from January to August 1993. Relative abundance of colonies, nest site preferences, colony dynamics, phenology and diet are described. Data quantifying vespulid wasp nest abundance in Manawatu between 1991-1994 were sourced from pest control companies and the Manawatu­ Wanganui Regional Council. These data were compared with rainfall records for the same period. Over 75 % of nests examined in urban and rural Manawatu were built by common wasps. This trend persisted through the season with German wasps accounting for no more than 28 % of nests reported in any one month. Most reports of wasps were made in January, with February and March also being high. Heavy rainfall in spring appeared to promote colony formation in the following year.
