## What is Merestone?

Merestone runs the constraints check of an environmental desktop review: drop a pin, set a radius, get results by distance and direction and a dated PDF with sources and licenses, on iPhone, iPad and Mac. Not a field survey, a wetland delineation, an IPaC official species list or an agency determination.

UNITED STATES
Free, with a 250 m search: PAD-US protected and conserved lands, National Wildlife Refuge System boundaries, and FWS wilderness and proposed wilderness.

With a purchase or subscription, for NEPA screening, Section 7 consultation prep and the environmental setting of a Phase I ESA:
• ESA critical habitat, final and proposed (FWS, NOAA Fisheries); listed species ranges (EPA snapshot)
• NWI wetlands and deepwater habitats, a first look before delineation
• FEMA flood zones in Washington, DC (SFHA and 0.2% annual chance) with DC's modeled rain scenarios; a Massachusetts NFHL snapshot of uncertain date
• California Fire Hazard Severity Zones (SRA effective 2024, LRA recommended 2025); MTBS burned areas 2024
• National Register of Historic Places, EPA Superfund site boundaries, sole source aquifers
• Federal lands: NPS, National Forests, roadless areas, BLM wilderness and WSAs, ACECs, Wild and Scenic Rivers, surface management agency, PLSS
• Water: NHD streams and waterbodies, HUC-12 subwatersheds, EPA ATTAINS assessed waters
• National marine sanctuaries, state MPAs, West Coast EFH and HAPCs
• USGS geology and Quaternary faults; SSURGO soils and NLCD land cover (map images)
• American Indian and Alaska Native lands (BIA), and more in the app

WGS84 UTM coordinates; app and PDF report in English. US layers need an internet connection.

BUYING
Merestone Worldwide is a subscription to every country and region, including any added later. A free 7-day gift unlocks them all once, with no renewal and nothing to cancel. Or buy a country, region or bundle once in the app (North America: United States, Canada and Mexico). Free: a set of protected areas everywhere, with a 250 m search. PDF export, the wider radius and offline downloads of eligible layers need a purchase or subscription; US, national Canadian and Swiss layers work online only. Merestone is independent of agencies.

DATA AND LIMITS
Public records are incomplete and may withhold sensitive species; empty is not proof of absence. Map-image layers cannot be downloaded or radius-searched. Not in the app yet: nationwide FEMA flood zones (DC and the Massachusetts snapshot only), state Natural Heritage records. Confirm the official record before relying on it.

### 2.12.1 — 2026-10-29

### 2.12.0 — 2026-10-27

New country: Mexico. Federal protected natural areas (ANP), certified voluntary conservation areas and Ramsar sites are free; a purchase or subscription adds mangroves, groundwater by aquifer, geology and INEGI maps. On Mexican devices the app and its PDF reports are in Latin American Spanish.

The USA and Canada bundle is now North America and includes Mexico: if you already own it, you get Mexico at no extra cost. Own the US or Canada? The app offers the rest as an upgrade.

New country: Japan, with a Japanese interface and reports. Ramsar sites, quasi-national parks and nature conservation areas are free; a purchase adds hazard zones, vegetation, geology and more.

New bundle: East Asia, Japan and Hong Kong together. Own one? The app offers the other as an upgrade.

Downloaded offline copies stay usable after app updates, so an update never makes you download them again, and the offline notice shows the date of your copies.

Layer names are now shown in the app's language throughout, and leftover English was fixed in several languages.
