Toolbox update 2: Creating bias grids for MaxEnt modelling

Let’s say you’ve been travelling across Peninsular Malaysia looking for a particular animal or plant over the years and you’ve marked the GPS coordinates of its presence through an indirect sign (e.g., tracks or vocalizations) or an actual sighting. And one day, you decide to make a map of its distribution, but of course, you do not have the time and effort to look in every nook and cranny of the peninsula to make an accurate map. So wouldn’t you like to know potential places where your species might be found? Over the years, scientists have developed a range of species distribution models (SDMs) to help you do just that. SDMs try to establish a relationship between your species records and the environmental or spatial characteristics (e.g., rainfall, temperature, forest cover, land use types, distance to water sources) of your sampling area (Franklin 2009). In other words, SDMs help to predict where you might find other suitable habitats for your species – you don’t always have to depend on luck to go find them! One of the more popular types of SDMs is Maximum Entropy Modelling Continue reading

Toolbox update 1: Uploading custom maps to Garmin GPS

Have you been frustrated trying to find out how to upload a custom map (e.g. with grid cells and topo maps) to your Garmin GPS? We have. There are always conflicting instructions on the internet and there’s no one website which explains the steps clearly. We’ve decided enough is enough!
