Zoom into the map until green forest patches appear, then click any patch to see its conservation tier and connectivity rating.
Toggle potential movement corridors using the "Show corridors" button at the top of the map.
To see full technical details, click the How to use this map button in the top panel.

This interactive map is a product of research examining landscape connectivity for arboreal wildlife across urbanisation gradients in Peninsular Malaysia.
Each forest patch is classified into one of six conservation tiers using a Patch Structural Quality Index (PSQI), which combines five patch-scale landscape metrics: total area, core area, contiguity index, perimeter-area ratio, and Euclidean nearest-neighbour distance. Connectivity values are derived from circuit theory modelling using Omniscape, which simulates the flow of movement current across the landscape under varying resistance assumptions.
The accompanying journal paper is currently in review.

Zoom into any part of the Klang Valley until green forest patches appear on the map. You can also use the search bar in the sidebar to jump to a specific location. Right-click and drag to tilt the map into 3D view, or drag with both fingers if using a mobile device. The map works best on a desktop browser.
Each patch is coloured according to its conservation tier, which reflects its structural quality as a habitat:
Use the "Filter by category" checkboxes in the sidebar to show or hide individual tiers on the map.
Click any forest patch to see its details in the sidebar. The panel shows the conservation tier, a plain-language description of what it means ecologically, the connectivity rating, and the distance to the nearest adjacent patch. Expand "Show technical details" to see the individual landscape metrics. Each metric has a small "i" button you can click for a plain-language explanation.
The connectivity potential rating is derived from Omniscape circuit theory modelling, which simulates how movement current flows across the landscape. High (cyan) indicates the patch has high connectivity potential, Moderate (yellow) indicates partial connectivity potential; Low (red) indicates high surrounding landscape resistance and low connectivity potential; Barrier (dark purple) indicates the patch is surrounded by effectively impermeable matrix, with no connectivity potential.
Click "Show corridors" to reveal lines connecting forest patches to their nearest neighbours. Each line is coloured by connectivity level. Use the High, Moderate, and Low buttons to toggle each level on or off. Click any corridor line to see details in the sidebar.
The URL in your browser updates automatically as you pan and zoom, so you can bookmark or share a link that opens the map at exactly the same position. Click the 🔗 Share button in the top bar to copy the current link directly to your clipboard.
Use the "Filter by patch area" tool in the sidebar to show only patches above or below a certain size in hectares. This can help you focus on large core habitats or identify which smaller patches are most at risk.
