Impatiens gomphophylla Baker subspecies cribbii Grey-Wilson
|Red List Category & Criteria:||Endangered B1ab(iii)+2ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC East African Plants Red List Authority|

As the habitat (near streams in grassland) in the largest part of its distribution area is declining in both extent and quality due to the suppression of regular burning and the discontinuing of grazing; and as one of the other locations is the scene of wholesale conversion to agriculture, we assess this taxon as Endangered.
|Range Description:||Known from 9 collections from 8 localities, all from Tanzania and collected 1905-2009, with two localities protected within Kitulo National Park and Ndukunduku Forest Reserve.|
Native:Tanzania, United Republic of
|Estimated area of occupancy (AOO) - km2:||79.8|
|Continuing decline in extent of occurrence (EOO):||Yes|
|Number of Locations:||3|
|Lower elevation limit (metres):||2000|
|Upper elevation limit (metres):||2180|

|Population:||Specimen label information for two collections: "very common" and "frequent". Specimens collected between 1905 and 2009.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||near streams in grassland, near stream in open area in forest. Herb to 1 m|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||There is no information on any use or trade.|
|Major Threat(s):||Most collections are from within Kitulo National Park, where the discontinuing of grazing and the halt of the regular burning is impacting grassland taxa. There is no protection of vegetation within Ndukunduku Forest Reserve. The Bulongwa area is heavily cultivated for wheat; conditions in Msima Stock Farm are unknown. From these observed threats we are deducting an ongoing decline in quality and extent of suitable habitat, as well as a decline of the EOO.|
|Conservation Actions:||There are no conservation actions in place.|
