This is a starting library, not a claim that every question is settled. We prefer primary agencies and peer-reviewed research; the short descriptions explain why each source belongs here.

Evidence labels
What our labels mean
Developing
Promising or informative, but not enough to treat as general proof.
Hypothesis
A testable Clutch0 question, not an instruction or a conclusion.
Unknown
Not adequately answered by the record currently collected here.
Regions & current management
Start locally.
Florida Fish and Wildlife Conservation Commission — Green Iguana
Established: FWC describes green iguanas as nonnative invasive in Florida and states that anti-cruelty laws and permit rules still apply. Use this before repeating Florida-specific legal or impact claims.
UF/IFAS — Florida’s Introduced Reptiles: Green Iguana
Established: Extension overview of Florida introduction history, ecology and documented interactions; it notes a 1960s introduction record and nesting/burrowing behavior.
Taiwan Forestry and Nature Conservation Agency — 2025 removal programme
Established: FANCA describes green iguanas as invasive, coordinated removal teams, real-time reporting and a public dashboard. It is a regional case study, not a transferable protocol.
Taiwan — Current status of invasive alien species management
Established: Agency description of invasive-species management that explicitly addresses humane-removal guidance and animal welfare.
USDA Forest Service — Puerto Rico farmer interviews
Developing: Research documenting farmer-reported direct and indirect effects. It is valuable evidence about reported experience, not a population-wide estimate.
USDA Forest Service — Experimental agricultural impacts and mitigation
Developing: Experimental work on agricultural effects and mitigation. Its findings should be read with its site and crop limits intact.
Research & conservation context
What management still needs to show.
State of knowledge for invasive green iguanas in Florida
Unknown: This review identifies pervasive research needs and calls for evaluation of relative efficacy and population impacts of methods including egg removal. That is why Clutch0 does not call reproductive intervention proven.
IUCN SSC Iguana Specialist Group — Position statement
Established: Conservation guidance supporting rapid, coordinated and humane action against detected non-native iguanas, with continuing management if eradication fails. Its context includes protecting native iguanas.
What we don’t know
Open questions are part of the work.
- 01Does systematic clutch removal measurably reduce recruitment or population growth?
- 02Which combinations of adult removal, exclusion, habitat work and reproductive-stage intervention create durable outcomes?
- 03What monitoring threshold distinguishes suppression from ecological recovery or eradication?
- 04When do genetics, native taxa or island-specific conditions make a generalized approach unsafe?
A standing invitation
Bring better evidence.
Corrections, primary records, methods data and well-documented negative results are welcome. Assertions without sources are not added to the record.
