Downloading Dominican Republic Protected Area Boundaries from the WDPA
The Dominican Republic has placed a substantial share of its territory under national parks and nature reserves. If you need those boundaries in a GIS, the first place to look is the WDPA (World Database on Protected Areas). This post walks through the whole process — from finding the country page to opening the shapefile in QGIS.
What the WDPA Actually Is
The WDPA is the most comprehensive global database of terrestrial and marine protected areas. It is a joint project between the UN Environment Programme (UNEP) and the International Union for Conservation of Nature (IUCN), compiled and managed by UNEP-WCMC in collaboration with governments, NGOs, academia, and industry.
Two things matter most in practice:
- It updates monthly. Submissions from governments and organizations are folded in every month, so you can always get a current release.
- It's free to use — with a mandatory citation requirement (more on that below).
Your access point is a website called Protected Planet. If the WDPA is the database, Protected Planet is the portal you browse and download it from.
Step 1 — Go to the Country Page
You don't need the entire global dataset. Protected Planet offers per-country pages, so you can pull just the Dominican Republic.
Enter this in your browser:
https://www.protectedplanet.net/country/DOMDOM is the country code for the Dominican Republic. One warning here. There's another Caribbean nation with a confusingly similar name: the Commonwealth of Dominica, code DMA. They are entirely different countries, and the English names are close enough that searching your way in can land you in the wrong place. Get in the habit of confirming by code.
The page opens with the country's protected area statistics. As of July 2026, the Dominican Republic has 141 protected areas on record.
One figure deserves a closer look: the Polygons/Points ratio. For the Dominican Republic it's 97% polygons, 3% points. Why that matters becomes clear in Step 4.
The page also reports that 37 of these areas have management effectiveness evaluations — a useful signal of whether an area is merely designated on paper or actually being managed.
Step 2 — Download and Pick a Format
Click the Download button in the top right of the page. This is how WDPA data is served.
You get two format choices:
| Format | What it is | Recommendation |
|---|---|---|
| Shapefile (SHP) | The de facto GIS standard. Opens cleanly in QGIS | ⭐ Pick this for QGIS |
| File Geodatabase (GDB) | ESRI ArcGIS format | Only if you're in an ArcGIS workflow |
Working in QGIS? Take the Shapefile.
Step 3 — Terms of Use and Citation
A terms-of-use screen appears before the download starts. It looks like a formality, but the WDPA carries a mandatory attribution requirement. If you produce anything from this data — a paper, a report, a map — you must include a citation like this:
UNEP-WCMC and IUCN (2026). Protected Planet: The World Database on
Protected Areas (WDPA). Cambridge, UK: UNEP-WCMC and IUCN.
Available at: www.protectedplanet.net
(dataset downloaded 2026/07)The country profile page also supplies a country-specific citation at the bottom. If you're only using national-level data, that's the more precise one to use.
Write down the month and year you downloaded it. The WDPA changes every month, so "which vintage is this?" is part of the data's identity. Redraw the same map six months later and your numbers may shift.
Step 4 — The ZIP Inside the ZIP
This is where people usually pause and wonder if something went wrong. Unzip your download and you'll find more ZIP files inside. That's not a mistake — it's how the WDPA is packaged.
The inner ZIPs are numbered _0, _1, _2. They are not split by geometry type — the shapefile is simply cut into three equal parts because of its size. The Shapefile_splitting_README.txt bundled alongside them says exactly this. So extract all three. Take only one and you're holding a third of the data.
Inside each part you'll find two sets of shapefiles, separated by geometry type:
Polygons (-polygons) — protected areas whose boundaries are mapped as actual areas. This is the boundary data you came for.
Points (-points) — protected areas represented by a single coordinate, because no boundary has been submitted. The reported size may be known, but the actual outline isn't in the database yet.
Now that 97% / 3% figure from Step 1 makes sense: 97% of Dominican protected areas (137 polygons) have real mapped boundaries, and 3% (4 points) exist only as dots. Together that's 141 — an exact match for the count on the country page. A higher polygon share is a good sign about a country's spatial data quality — and the Dominican Republic looks solid on this front.
So if boundaries are your goal, extract all three parts, collect the three polygons shapefiles, and merge them into one in the next step.
New to shapefiles? A
.shpdoesn't travel alone. It moves as a set —.shp,.dbf,.shx,.prj, and others. Move the whole folder, and never copy just one piece.
Step 5 — Open It in QGIS
With the files extracted, open QGIS and go to:
Layer ▶ Add Layer ▶ Add Vector Layer, then point it at the -polygons.shp files from all three parts. The CRS is WGS 84 (EPSG:4326) and the encoding is UTF-8.
Then stitch the three pieces together:
Vector ▶ Data Management Tools ▶ Merge Vector Layers
Select the three polygon layers and merge them into one, and you'll have a single layer of 137 features. If you need the points too, run the same operation once more on those. Save the result as a GeoPackage (.gpkg) — it's more robust than a shapefile and free of the field-name length limits.
Protected area boundaries across the Dominican Republic now appear on the canvas. Open the attribute table and you'll find each polygon carries its name, IUCN management category, year of designation, reported area, and designation type. Style by a field like NAME or DESIG and you can color national parks separately from scientific reserves at a glance.
Worth Knowing — the WDPA and National Data Won't Always Match
One last thing that matters in real work.
The WDPA is a secondary compilation: UNEP-WCMC takes what countries submit and harmonizes it to an international standard. The Dominican government separately maintains and publishes its own dataset through SINAP (Sistema Nacional de Áreas Protegidas — the National System of Protected Areas).
The two generally agree, but they can diverge, for a few reasons:
- Lag. When a government revises a boundary, it takes time to reach the WDPA. There may be a February 2026 national revision while the WDPA still carries an earlier version.
- Methodology. Different base maps or area-calculation methods produce small numerical differences.
- Counting rules. When an international designation (World Heritage, Ramsar) overlaps a national one at the same site, the WDPA counts each designation as a separate protected area. This is why WDPA totals often look higher than the government's own published count.
So which should you use?
- Comparing across countries, or reporting in an international context → the WDPA. Its strength is that the whole world is organized on one standard.
- Domestic policy, permitting, or fieldwork in the Dominican Republic → the national SINAP data. That's where legal force lives.
The best move is to load both into QGIS and overlay them. Once you can see exactly where they disagree, it's usually obvious which one your work needs.
Summary
- Go to
protectedplanet.net/country/DOM(don't confuse it with Dominica'sDMA) - Download button, top right → choose Shapefile
- Accept the terms; record the citation and your download date
- Inside the ZIP, extract all three numbered ZIPs and collect the
polygonsshapefiles - In QGIS: Layer ▶ Add Layer ▶ Add Vector Layer → open the
.shpfiles → Vector ▶ Data Management Tools ▶ Merge Vector Layers to combine the three parts
It's a five-minute job. Just don't skip the two things that cause trouble later: merging every part and telling polygons from points in Step 4, and logging your citation in Step 3.
