CoP17 Prop. 25A) Inclusion of the following species of the Genus Abronia into Appendix I:
Abronia anzuetoi, A. campbelli, A. fimbriata, A. frosti and A. meledonaB) Inclusion of the following species of the Genus Abronia into Appendix II:
Abronia aurita, A. gaiophantasma, A. montecristoi, A. salvadorensis andA. vasconcelosii
An annotation is also proposed:a) for zero quota for wild specimens, andb) zero quota for captive bred specimens from non-range Sates. This annotation would allow for
captive-bred exports from range StatesProponent: Guatemala
Summary: The genus Abronia, known as alligator lizards or abronias, are medium-sized insectivorous
arboreal lizards from Mexico (MX) and northern Central America (El Salvador (SV), Guatemala (GT), andHonduras (HN). They mainly inhabit montane cloud forests where they are associated with epiphytes in the
canopy of tall mature oak or pine trees. They give birth to between one and twelve live young once a year.
This proposal considers ten species that are found in Guatemala, El Salvador and Honduras. A second
proposal at CoP17 submitted by Mexico and the European Union proposes the inclusion of all species ofAbronia in Appendix II. See analysis of CoP17 Proposal 26 for a discussion of the genus as a whole.
Inclusion in Appendix I
Abronia anzuetoi (GT): Only known from one patch of forest with an area of 24km2 1. No information onpopulation size or trends. No major threats known. Reported in pet trade in China and Switzerland (seeCoP17 Proposal 26). Classified in the IUCN Red List as Vulnerable (2014).
Abronia campbelli (GT): Only known from one patch of forest with an area of 18km2 and an estimatedpopulation of 500 individuals2. There is ongoing habitat loss and degradation from cattle ranching. In 2010,
47 individuals were confiscated from an illegal pet market in Mexico3. Known illegal trader has asked locals
about this species within its native range4. Classified in the IUCN Red List as Critically Endangered (2013).
Abronia fimbriata (GT): Known from four locations with an extent of occurrence of around 1500km2. Nodata on population status or trends. There is continuing decline in the extent and quality of its habitat due toconversion to agriculture, and collection of ornamental plants 5. There is evidence online of international trade
for the pet market. Classified in the IUCN Red List as Endangered (2014).
Abronia frosti (GT): Only known from a few specimens at one location which is a patch of forest 0.7km2 inarea. No information on population size or trends. It is reported to be subject to continuing decline in theextent and quality of its habitat due to logging for firewood. A trader has asked locals about this species
within its native range4. Classified in the IUCN Red List as Critically Endangered (2013).
Abronia meledona (GT): Limited to one area with an extent of occurrence of less than 900km2. No
information on population size or trends. It is subject to continuing decline in the extent and quality of its
habitat due to agricultural activities. A known illegal trader has asked locals about this species within its
native range4. Classified in the IUCN Red List as Endangered (2013).
Inclusion in Appendix II with a zero quota for wild specimens and a zero quota for captive-bred
exports from non-range States
Abronia aurita (GT): Only known from one locality with an extent of occurrence of approximately 400km2.
No information on population status or trends. The forest where it is found is reportedly heavily fragmentedand degraded. Three specimens of this species were seized in 2009 hidden in video cassette in UK, on routefrom Guatemala to Czech Republic6. Classified in the IUCN Red List as Endangered (2013).
Abronia gaiophantasma (GT): Known from fewer than five locations with an extent of occurrence ofapproximately 750km2. Described as uncommon, population trend unknown. Reported to be affected by1

CoP17 Prop. 25
habitat loss. Evidence online of international trade of this species. Classified in the IUCN Red List asEndangered (2014).
Abronia montecristoi (SV, HN, GT): Known from two locations of intact forest, with an extent of occurrenceof approximately 800km2. Not recorded recently, despite the area where it occurs being well surveyed forreptiles7. There is ongoing destruction of old growth forest where it is found in Honduras; habitat inEl Salvador is reportedly better preserved8. Classified in the IUCN Red List as Endangered (2013).
Abronia salvadorensis (HN): Only known from a few specimens. Recorded from two locations with anextent of occurrence of up to 200km2. Likely to be affected by habitat loss and degradation. Classified in theIUCN Red List as Endangered (2013).
Abronia vasconcelosii (GT): Known from 10 localities with an extent of occurrence of about 2500km2.
Previously described as common, the population is thought to be in decline as much of the land has been
converted to agriculture since the 1990s. Reported trade of this species in Czech Republic and United
Kingdom and advertised for sale online. Classified in the IUCN Red List as Vulnerable (2013).
Abronia species are in trade for the exotic pet market. This trade is reviewed in the analysis of Proposal 26.
The great majority of recorded trade is in the Mexican A. graminea and most of the remainder in unspecified
Abronia spp9. Trade data records a small number of specimens imported with origin Guatemala, all forscientific purposes9.
There is no authorised collection for trade or commercial export of Abronia species native to El Salvador,Honduras and Guatemala. However there is reported commercial trade or evidence online of the sale ofA. anzuetoi, A. campbelli, A. fimbriata, A. aurita, A. gaiophantasma and A. vasconcelosii.
The range of all of these species overlaps with protected areas, although often only partially. There are
ongoing monitoring programmes in Guatemala, plus local education and awareness programmes. A captive
breeding program has begun for A. campbelli, A. frosti and A. meledona with some successful re-releases. In
Mexico there is at present captive-breeding in government Wildlife Management Units (UMAs) ofA. campbelli as well as a number of Mexican species; a private initiative in Mexico is also captive-breeding
A. vasconcelosii.
Analysis:
Inclusion of Abronia anzuetoi, A. campbelli, A. fimbriata, A. frosti and A. meledona in Appendix I
Available information indicates that Abronia anzuetoi, A. campbelli, and A. frosti all have small or very small
ranges in which there is said to be ongoing habitat degradation. These appear to meet the biological criteria
for inclusion in Appendix I in Res. Conf. 9.24 (Rev. CoP16).
Abronia fimbriata and A. meledona have more extensive distributions, although habitat in these is also
believed to be declining in quality and extent. There is no information on population levels or trends, otherthan the inference that populations are likely to be declining. There is insufficient information to determine
whether these species meet the biological criteria for inclusion in Appendix I.
There is international demand for Abronia species indicating that these species meet the trade criteria forinclusion in Appendix I.
Inclusion of Abronia aurita, A. gaiophantasma, A. montecristoi, A. salvadorensis and A.
vasconcelosii in Appendix IIThese species have known areas of occurrence ranging from 200km 2 to 2500km2. There is no information on
population levels or trends on any, other than an inference that population are likely to be declining owing todeclines in quality and extent of habitat. There are indications of trade in three of them (A. gaiophantasma,A. aurita and A. vasconcelosii). However such trade (which is illegal in wild-caught specimens from range
States) appears to be at a very low level and it seems unlikely that harvest for it will be reducing the species
to a level at which they may qualify for inclusion in Appendix I in the near future, or at which its survival might
be threatened by continued harvesting or other influences.
The proposal includes a zero quota for captive-bred specimens from non-range States. This is intended toreflect that no legal export for commercial purposes has been permitted for these species and therefore any2

CoP17 Prop. 25
founding stock of commercial captive breeding facilities is believed to have been imported illegally. There isno other example of such a restriction on trade in captive-bred specimens of Appendix-II listed species in theAppendices.
There is a great deal of variation within species, and it can be difficult to distinguish between some species.
Given that at least three of the species proposed here for listing in Appendix I appear to meet the criteria,then the other species meet the criteria in Annex 2 b of Res. Conf. 9.24 (Rev. CoP16) (lookalike).
