Recovery plans delineate reasonable actions which are believed to be required to recover and/or protect listed species. Plans are published by the U.S. Fish and Wildlife Service, sometimes prepared with the assistance of recovery teams, contractors, State agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director or Director as approved.

  • Moth Report for 2019
    CHESHIRE (VICE COUNTY 58) MOTH REPORT FOR 2019 Red-headed Chestnut: Nicola Ginn Authors: Steve H. Hind and Steve W. Holmes Date: March 2020 Cheshire moth report 2019 Introduction The warm southerly airflow across the British Isles in middle to late February resulted in record- breaking temperatures, with some species getting off to a flying start. There tends to be less moth trapping during this period and those who did not take advantage of this warm spell missed out on some good catches, the most unexpected of which was the first county record of Red-headed Chestnut Conistra erythrocephala at Styal. This was the first of a number of unusual migrants to reach Cheshire during the year, with five Small Marbled Eublemma parva arriving during July, followed by two Loxostege sticticalis, a Sitochroa palealis and two Bedstraw Hawk-moths Hyles gallii during the first three nights in August. Thirteen new species were added to the county list during 2019, Ectoedemia heringella, Phyllonorycter lantanella, Pseudatemelia josephinae, Aproaerema larseniella, Caryocolum viscariella, Mompha terminella, Cnephasia genitalana, Acleris cristana, Eana penziana, Aethes tesserana, Ancylosis oblitella, Cypress Pug Eupithecia phoeniceata and Red-headed Chestnut Conistra erythrocephala. This is a significant rise and a trend which we anticipate continuing thanks to global warming. Gone are the days when we were envious of those in the south; a large number of their previously understood to be ‘southern regions’-only species are slowly (some more quickly) making their way here. A list of all the 451 new records can be found in the Species new for their respective 10km squares in 2019 section towards the end of this report.

  • (Aspleniaceae) in the Maltese Islands
    Fl. Medit. 26: 69-80 doi: 10.7320/FlMedit26.069 Version of Record published online on 7 November 2016 S. Mifsud, M. Napier, S. Fenech & L. F. Cassar Current status of Asplenium sagittatum (Aspleniaceae) in the Maltese islands Abstract Mifsud, S., Napier, M., Fenech, S. & Cassar, L. F.: Current status of Asplenium sagittatum (Aspleniaceae) in the Maltese islands. — Fl. Medit. 26: 69-80. 2016. — ISSN: 1120-4052 print- ed, 2240-4538 online. Asplenium sagittatum is a rare, indigenous fern which was assumed extinct in the dated Maltese Red Data book until 2008 when a small number of individuals was rediscovered. New records of this fern are reported, including a large and important population located in the north of mainland Malta. For the first time, the anatomical characters of Maltese material are described and compared with those of material from central Europe. The paper also presents taxonomical clarifications dealing with A. scolopendrium, as also the results of a local Red List assessment for this endangered fern. Key words: Asplenium scolopendrium, flora of Malta, Central Mediterranean region, Red List, pteridophytes, ferns. Introduction Ten species of ferns are listed in the inventory of Maltese flora, with the latest addition being an endemic subspecies of Polypodium vulgare L. (Peroni & al. 2013). The following pteridophytes are known to occur in the Maltese islands: Selaginella denticulata (L.) Spring (rare), Equisetum ramosissimum Desf. (frequent but of localized distribution), Adiantum capillus-veneris L. (frequent), Anogramma leptophylla (L.) Link (locally fre- quent), Asplenium sagittatum (DC) Bange (rare), A. ceterach L. (rare), A. trichomanes L. (rare), A. marinum L. (very rare), Pteridium aquilinum (L.) Kuhn (very rare) and Polypodium vulgare subsp.
