1 IUCN (International Union for Conservation of Nature) We are working on a contract with National Grid to undertake a first year of survey for wild blue lupines and Karner blue butterflies/Frosted Elfins under National Grid’s new Habitat Conservation Plan…..nearly final and approved. Yea!!! Anyways, do you have any students in mind that might want to spend mid-May to mid-June, and perhaps longer, mapping lupines and conducting presence/absence butterfly surveys in the Queensbury, Saratoga, Albany Area? If they are from here originally and could live with family that would be great. They need to have a valid driver’s license. I am looking for two such students.

2 IUCN (International Union for Conservation of Nature) NYSDEC Division of Fish, Wildlife and Marine Resources: 42 paid internships available for SUNY-ESF Students! The New York State Department of Environmental Conservation’s Division of Fish, Wildlife and Marine Resources has just added 16 more paid internships to the 26 already available for the 2012 season for SUNY-ESF students. The following 42 internship opportunities are now available for the spring/summer season: New internships are highlighted in gray. If you have already applied you may reapply for the new ones. No internships have yet been filled. Many internships now have detailed descriptions.www.esf.edu/efb/gibbs/NYSDEC_2012.htm Currently enrolled students can work for up to 20 weeks and up to 800 hours. Students must be enrolled in fall semester 2012 to be eligible. Pay rate is $10/hr for undergraduates and $15/hr for graduate students. If you are interested in applying for any of these positions, please send as a single document.pdf attachment to an to –a short cover letter that identifies the specific internship(s) you wish to be considered for (please identify position number) and outlines your qualifications and interest in each –includes a resume with your contact information ( and phone).

15 IUCN (International Union for Conservation of Nature) Introduction to the IUCN Red Listing Process

16 IUCN (International Union for Conservation of Nature) The IUCN Red List Categories & Criteria All materials are freely available on IUCN Red List web site:

17 IUCN (International Union for Conservation of Nature) CR A2ace;B1ab(iii) Category: Critically Endangered Rabb’s Fringe-limbed Treefrog Ecnomiohyla rabborum Criteria & subcriteria

18 IUCN (International Union for Conservation of Nature) The IUCN Categories Not Evaluated (NE) Near Threatened (NT) Data Deficient (DD) Endangered (EN) Critically Endangered (CR) Vulnerable (VU) Extinct in the Wild (EW)Extinct (EX) Least Concern (LC)

19 IUCN (International Union for Conservation of Nature) A taxon is Extinct when there is no reasonable doubt that the last individual has died. Dodo, Raphus cucullatus Extinct (EX)Extinct in the Wild (EW) A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range.

20 IUCN (International Union for Conservation of Nature) A taxon is threatened when the best available evidence indicates that it meets any of the criteria A to E for the thresholds stated in one of the three threatened categories: Critically Endangered, Endangered or Vulnerable. Critically Endangered (CR) CR taxa are considered to be facing an extremely high risk of extinction in the wild Mandrinette, Hibiscus fragilis Photo © Wendy Strahm Endangered (EN) EN taxa are considered to be facing a very high risk of extinction in the wild Black-browed Albatross, Thalassarche melanophrys Photo © Tony Palliser Vulnerable (VU) VU taxa are considered to be facing a high risk of extinction in the wild Golden Pagoda, Mimetes chrysanthus Photo © Craig Hilton- Taylor

21 IUCN (International Union for Conservation of Nature) Near Threatened (NT) A taxon is Near Threatened when it has been evaluated against the criteria and does not qualify for CR, EN or VU now, but is close to qualifying for or is likely to qualify for a threatened category in the near future. Macaronesian Laurel, Laurus azorica Photo © H. Fraga Least Concern (LC) A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for CR, EN, VU or NT. Widespread and abundant taxa are included in this category. Olive Baboon, Papio anumbis Photo © Caroline Pollock

22 IUCN (International Union for Conservation of Nature) Data Deficient (DD) A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. Tree Tomato Solanum [Cyphomandra] betacea Not Evaluated (NE) A taxon is Not Evaluated when it has not yet been evaluated against the criteria

23 IUCN (International Union for Conservation of Nature) The IUCN Red List Criteria

24 IUCN (International Union for Conservation of Nature) A Population reduction B Restricted geographic range C Small population size & decline Very small or restricted population D E Quantitative analysis CRITERIA Quantitative thresholds THREATENED CATEGORIES Critically Endangered (CR) Endangered (EN) Vulnerable (VU) Nature of the Criteria

25 IUCN (International Union for Conservation of Nature) Why use multiple criteria? All taxa being assessed must be evaluated against each criterion. Meeting any one of the criteria qualifies a taxon for listing at that level of threat All criteria met at the highest level of threat should be listed. Not all the criteria are appropriate to all taxa.

26 IUCN (International Union for Conservation of Nature) Time Population Size Criterion A Past, present or future population reduction

27 IUCN (International Union for Conservation of Nature) Based on any of four criteria: A1: Population reduction in past and causes of decline now ceased A2: Population reduction in past and causes of decline ongoing A3: Population reduction expected in future A4: Population reduction in past AND future Criterion A

28 IUCN (International Union for Conservation of Nature) Criterion B Restricted geographic range and fragmentation, continuing decline or extreme fluctuations

29 IUCN (International Union for Conservation of Nature) Based on either of two sub-criteria: B1: Estimated extent of occurrence AND / OR B2: Estimated area of occupancy Criterion B AND at least TWO of a-c: a. Severely fragmented or few locations b. Continuing decline c. Extreme fluctuations

30 IUCN (International Union for Conservation of Nature) Criterion B Subcriterion B1 Extent of occurrence estimated to be: EN VU < 100 km² < 20,000 km² < 5,000 km² Subcriterion B2 Area of occupancy estimated to be: CR < 10 km² < 500 km² < 2,000 km²

31 IUCN (International Union for Conservation of Nature) Criterion B a. Severely fragmented or # locations: EN VU  10 5 5 5 51 CR AND at least TWO of a, b or c: b. Continuing decline in any of the following : (i) (i)EOO (ii) (ii)AOO (iii) (iii)Area, extent and/or quality of habitat (iv) (iv) # locations or subpopulations (v) (v)# mature individuals c. Extreme fluctuation in any of the following : (i) (i)EOO (ii) (ii)AOO (iii) (iii) # locations or subpopulations (iv) (iv) # mature individuals

32 IUCN (International Union for Conservation of Nature) Small population size and continuing decline Extinct Criterion C

33 IUCN (International Union for Conservation of Nature) Based on small population size AND either C1 or C2: Criterion C C1: Continuing decline in population size at a specified rate OR C2: Continuing decline in population size at any, unspecified rate AND either C2a or C2b: C2a:(i) very small subpopulations, OR (ii) most mature individuals are in one subpopulation C2b:extreme fluctuations in number of mature individuals

34 IUCN (International Union for Conservation of Nature) Criterion C Thresholds for criterion C Population size is estimated at: EN VU < 250 mature individuals CR < 2,500 mature individuals < 10,000 mature individuals

35 IUCN (International Union for Conservation of Nature) Criterion C Subcriterion C1 Estimated continuing decline of: EN VU  25% within 3 years or 1 generation CR  20% within 5 years or 2 generations  10% within 10 years or 3 generations

36 IUCN (International Union for Conservation of Nature) Criterion C Subcriterion C2 Observed, projected or inferred continuing decline at any rate EN VU < 50 mature individuals CR < 250 mature individuals < 1,000 mature individuals AND at least one of the following: C2a(i). All subpopulations have:  90% of the mature individuals  95% of the mature individuals 100% of the mature individuals C2a(ii). One subpopulation contains: C2b. There are extreme fluctuations in number of mature individuals.

37 IUCN (International Union for Conservation of Nature) Very small or restricted population Criterion D

38 IUCN (International Union for Conservation of Nature) Criterion D Criterion D is split into D for the CR and EN categories; and D1 and D2 for the VU category. EN VU < 50 mature individuals CR < 250 mature individuals < 1,000 mature individuals D. Total current population size estimated as: D1. Total current population size estimated as: D2. The population has a very restricted AOO (typically <20 km²) or is known from very few locations (typically ≤5). NOTE: for the VU D2, there should be a plausible threat that is likely to rapidly affect the population.

39 IUCN (International Union for Conservation of Nature) Quantitative analysis = oh ohh! Criterion E

40 IUCN (International Union for Conservation of Nature) Based on quantitative analysis showing a probability of extinction in the wild is at least: Within 10 years or 3 generations Within 20 years or 5 generations Within 100 years 50% Critically Endangered 10% Vulnerable 20% Endangered Up to a maximum of 100 years in the future Criterion E
