About GrassPro

GrassPro Southern Africa is a smart mobile tool that helps you identify grasses and provides a wealth of ecological and agricultural information on each species. It contains a comprehensive content-rich database with written and taxonomic information, distribution maps, illustrative photographs, and other useful content.

What sets this app apart is that it filters and ranks your grass species list during a search, using the innovative, intuitive and interactive award-winning “Smart Search” function. It further includes GPS functionality to indicate the grass species occurring in your immediate vicinity.

GrassPro is a collaborative initiative by grass expert Frits van Oudtshoorn and well-known app developer SmartSearch Apps. It was officially launched on 26 July 2023 during the 58th annual congress of the Grassland Society of Southern Africa (GSSA).

App Functions in Detail

Below is an overview of each main function available in GrassPro.

Grass identification is made easy with the Smart Search function. You can identify a grass using various features (plant height, inflorescence type, spikelet type, leaf width, etc.). Going through this process will bring up a list of grass "candidates", arranged from most to least likely the grass you want to identify. The Smart Search function also allows you to create grass lists and combined lists on features such as uses (pasture grasses, ornamental grasses, thatching grasses, lawn grasses, etc.), ecological info (grazing value, plant succession, ecological index, weeds and invaders), geographical status (endemic, indigenous and non-indigenous), world distribution, and taxonomic ranking (subfamily and tribe).
