Pest and disease survey, map and reporting tools by country

This page reports what each tool's own page says. It is not a diagnosis of any tree and does not say what should be done with one. Each section names its source, all read on October 9, 2026. The maps themselves are on the linked sites and none is embedded here. Hotlines and offices for each country are on the report-a-pest pages: United States, Canada, United Kingdom and Australia. This page covers the survey and map layer only.

The five tools

Tool	What the page says
United States: Forest Health Protection, US Forest Service	What it is: a part of the State, Private, and Tribal Forestry area of the US Department of Agriculture Forest Service, with over 250 specialists in forest entomology, forest pathology, invasive plants, pesticide use, survey and monitoring, suppression and control, and assessment. What it does: technical assistance on forest health, including native and non-native insects, pathogens and invasive plants, and survey and monitoring information on forest insects, diseases and invasive plants. Who may report: the page read gives no reporting form. It lists a Mapping and Reporting Tools section, a Forest Health Monitoring section and a Contacts section.
United States and Canada: EDDMapS	What it is: a web-based mapping system for documenting invasive species and pest distribution, launched in 2005 by the Center for Invasive Species and Ecosystem Health at the University of Georgia, covering the entire United States and Canada. It gives over 9.3 million records as of October 2026. What it does: collects sightings as a national network, with maps at state, county and individual population level, a species locator and a query tool. Who may report: users enter observations in an online form or in smartphone apps, and the site invites registration. It says all data is reviewed by verifiers before it appears on maps, and that the data is freely available to everyone.
Great Britain: TreeAlert	What it is: the reporting site of Forest Research for suspected tree pests and diseases found anywhere in Great Britain. On the same page, Forest Research's Tree Health Diagnostic and Advisory Service is named as giving advice and, where possible, diagnosis. What it does: the site says it gathers tree health information used to follow up findings, identify trends of spread, direct surveys for regulated or quarantine pests and support management. It offers a general report, reports for specific problems such as ash dieback, acute oak decline, Dothistroma needle blight and oak processionary moth, and a report for damage not caused by a pest or disease. It links a Chalara map showing 10 km squares where ash dieback is confirmed, and Observatree, a citizen science early warning system. Who may report: the page does not restrict reporters. A report goes through a series of questions about the observation.
In Canada: Invasive pests and plants, Canadian Food Inspection Agency	What it is: the agency's hub for invasive insects, plants, plant diseases, and nematodes, snails and other pests, with a Report a plant pest sighting link. What it does: the page lists identification pages, domestic plant protection measures, a list of regulated pests in Canada, and plant pest surveillance, which it describes as annual plant health surveys across Canada to detect and monitor invasive species. Who may report: the page says protecting plant health in Canada is a shared responsibility and does not name who may use the report link.
In Australia: Reporting suspect pests, Plant Health Australia	What it is: the national page on reporting, which sends a report to the relevant state or territory agriculture agency through the Exotic Plant Pest Hotline 1800 084 881. What it does: the page says the hotline connects the caller to the authority of the chosen state or territory, which asks what was seen, when it was first noticed, where, and how widely distributed. Hours differ by jurisdiction, and the page lists offices for New South Wales, the Northern Territory, Queensland, South Australia, Tasmania, Victoria and Western Australia. Who may report: it names researchers, growers and members of the public, and says any unusual plant pest or disease should be reported immediately.

What the pages share and where they differ

EDDMapS and TreeAlert both put a person or an expert in the loop: EDDMapS has verifiers review data before it appears on a map, and Forest Research's ash dieback page says every TreeAlert report is assessed though it cannot answer each one. That page also says TreeAlert and TreeCheck both require clear, well-lit, close-up photographs. The Australian page says suspect material should generally not be moved, and samples not collected, without advice from the state or territory department, because incorrect handling could spread the pest or spoil the sample.

Northern Ireland sits outside TreeAlert: Forest Research says it uses TreeCheck, the all-Ireland tree disease reporting tool, on its ash dieback page. New Zealand and Ireland have their own pages in the report-a-pest set: New Zealand and Ireland.
