KLEE data archive

These data archives are available for public use. If you wish to use these data, we do ask that you contact us to facilitate the process.

Regardless of authorship, any publication using data from the plots should acknowledge* the KLEE project and its funders.  Depending on the level on involvement and the use of long-term records, co-authorship may also be appropriate.  We would appreciate it if any manuscript arising from these data were sent to Truman Young before submission for publication, to ensure data accuracy.

These data are also archived at Mpala Research Centre, again available for public use.

Understory vegetation surveys

These data include semi-annual (1998-2010) and annual (1998-present) surveys of the understory vegetation in all 18 KLEE plots. The full form of this data is archived as an Microsoft Excel Workbook.

Acacia drepanolobium densities and size distributions

Acacia drepanolobium tree density, surveyed in May 2011, in each of the 18 KLEE plots. Coming soon: GPS mapping points for oevr 20,000 tress in KLEE, from Spring 2015.


This Excel workbook has rainfall data from each of the three replicate KLEE blocks. There are separate worksheets for daily rainfall (since 2003), monthly rainfall (since 1996), and yearly rainfall (since 1996). There are a few gaps in the 1996-7 data.

Dung surveys

Semi-annual dung count data (2006-2011) from the KLEE plots, which are indicative on wildlife use, in each of the 18 KLEE plots.

Tree density experiment data

This Excel workbook has data (2006-2010) on herbivore use (dung counts, camera trap data), grass community composition, grass nutrients, grass production, and visibility in experimental plots (outside of KLEE but in the same ecosystem) in which tree density was experimentally manipulated in 2006.
