Informal interviews with elders from different age groups were carried out to discuss grazing patterns and use o f the forest during their moranhood. The age groups interviewed are summarised in Table 3.1. Interviewees were asked questions about the history o f grazing controls before and after the colonials came to the area where possible, the main grazing areas throughout the year and use o f the forest for grazing and water throughout the year.

The results from the two villages are very similar. The mean weighted ranks for each village and for men and women were correlated against each other using Spearman’s coefficient o f rank correlation (rg) (Siegel & Castellen, 1984). In both cases, the two groups were significantly similar in the way they ranked the various categories o f wild resource use (between villages, rs=0.96, P<0.001 ; between men and women, Vs = 0.94, P<0.001). Looking at the data it is clear that livestock use o f forest, both for cattle and smallstock, ranks very highly. It is important to note, however, that at the time of the baseline surveys, the local population knew that the study was interested in
livestock use o f the forest. It is possible that this may have resulted in an overestimate o f the importance o f the forest to livestock.
3.3.2.2 Current use o f forest by cattle
Livestock census
The results o f the livestock census from January 1994 are shown in Table 3.3 below. Given that the cattle were taken for water every day or every other day, the data covers two complete days. The final total for the number o f cattle using the water holes could then be calculated by adding the total number o f cattle which took water on the first day with the number o f cattle which only took water on the second day.
Table 3.3 Results o f the livestock census carried out at 14 water holes in and around the Leroghi Forest Reserve at Ngorika in January, 1994. The water holes weree watched from 8.30am until 6pm.

^ Data from interviews with the herders responsible for each herd at the water point. The census suggests there were approximately 6,900 cattle and 3,800 smallstock using the 17 water holes under observation at the time. O f these, 38% o f the cattle came from outside Angata Nanyukie Group Ranch whereas none o f the small stock counted were from elsewhere.
A much greater proportion o f cattle were reported to be regularly grazing in the forest than small stock: 87% o f cattle, compared to 53% o f smallstock. It was not specified whether this “forest” was inside or outside the forest reserve. However, only 19% o f
the small stock counted (717) were counted inside the reserve, the remainder all being counted at the three waterholes outside the reserve. O f the smallstock counted inside the reserve, they were only seen at 6 o f the 14 waterholes, all o f which were very close to the edge. In comparison, 71% o f the cattle (4,871) were counted at 14 waterholes inside the boundaries o f the forest reserve. This corresponds well with my
observations that small stock were using forest and bush areas, but almost entirely outside the reserve compared to cattle which were present in large numbers well within the boundaries o f the reserve.

There were considerable differences between the individual animals followed and in the case o f the animals followed in January, between the diet composition during the morning and during the afternoon. With such small sample sizes it would be difficult to carry out any meaningful statistical tests. However, there are still clear trends in the data.
Comparing the data up to 2.30pm, the proportion o f herb species in the diet was consistently higher in January than in April, whereas the opposite was true o f grass
species. This is as would be expected given the greater availability o f fresh grass in April following the first rains o f the season. There is no such clear pattern when comparing the proportion o f woody species in the diet. Individual animals varied considerably in the proportion o f woody species in the diet, intake ranging from 7% to 30%, and there is considerable overlap in the data from the two months. The overall average proportion o f browse species in the diet was 18%.
The proportion o f grass in the diet increased considerably after 2.30. One o f the reasons given as to why the cattle only used the forest in the dry season was that too much “segeet” (the vernacular name given to a range o f herbaceous species eaten by cattle) was not good for the cattle. The habitat selection data suggests that cattle are herded out o f the forest in the afternoon to increase roughage intake in the form o f dry grass.
O f all observations o f browsing, 76 were o f tree species and 82 were o f shrub species. Seven tree species were seen being browsed and 12 shrub species. The number of observations for each species is shown in Table 3.5 below.

Table 3.6 below shows habitat selection over the five follows. Comparison o f the data up to 2.30 only shows considerable difference between the two periods. The
much greater during January than in April. Forest edge and glade were used more in April than in January. In April, more time was spent in forest edge and glade than in any other habitat type. It is interesting to note that habitat selection in the afternoon in January differed considerably from the morning, with less use made o f closed forest and more made o f forest edge and glade areas. This accounts for the higher
proportion o f grass in the diet seen in Table 3.4. All o f these results should be interpreted with caution given the very low sample size.
Almost six thousand cattle were regularly taken to the forest at Saanata for grazing or water. Saanata itself covers an area o f roughly 4,460ha and it is clear that cattle do not go into the interior o f the forest block. If the cattle use between 50% and 75% o f the forest area (this is probably an overestimate), and spend 50% o f their day in the forest every other day, there was a density o f between 0.45 and 0.7 cattle per ha per day using the forest at the peak o f the dry season in 1994.

Figure 3-2 Total num ber o f faecal piles counted along the transect at Sordon by species and date o f survey
The graphs show the accumulative number o f dung piles found over the four survey periods. The results show:
1. Other herbivores present in the forest were mainly buffalo, elephant, bushbuck, waterbuck and eland. Evidence o f red duiker and reedbuck was also found as were sign o f baboon, warthog, bush pig, tree hyrax, hyena, leopard and lion.
2. Cattle did not use the area around Sordon during the dry period from 1993 - 1994, while cattle presence around Lorubai was comparatively high. This confirms the assertion made by the informants that cattle rarely if ever use the area around Sordon.
3. Use o f the forest by smallstock is low, the few pellets that were seen being limited to the first plot, located at the very edge o f the forest.
4. The presence o f cattle appears to suppress the density o f other wildlife, particularly buffalo.
5. Use o f forest by cattle is highly seasonal, with very little evidence o f cattle using the forest in January 1995 compared to January 1994. The rains from March/April
1994 had been very good and rangeland quality around the Lerroki Plateau was still relatively good in January 1995 (Drought Monitoring Programme Report, 1994 and pers obs.).
3.3.2.4 Historical use o f the forest fo r cattle grazing
The results o f the informal interviews with elders o f different age groups are summarised in Table 3.7.

Rule makers and enforcers
Elders
Elders would say when cattle could enter the forest
Would leave the forest during the wet season because the grass outside was better for the cattle and there was plenty o f water.
Elders
“when the time came, the elders would meet from around and go to the forest to pray for rain. At that time the cattle could go to the forest. After the rains everyone would come out. They would hold a meeting to make sure that no-one was still inside” There was never a forest guard. If a moran loses a cow inside [the forest] when the elders have not permitted them to enter he will be punished
Elders and government
1960 - 1966 they would need to get permission from the elders to use the forest.
1966 - 1984 it was illegal to enter the forest. Few people admitted to using the forest so no-one knew how many were inside” “People would sneak in every year”
“when it was illegal to enter the forest, no-one had authority to allow grazing so no-one would ask”
Rules were enforced by government guards & people were chosen to live close to the forest to control forest use.
Elders and government
These days when there is no grass the elders must meet with the government to decide to open the forest.
The elders gave permission
If a moran was repeatedly caught in a part where he was not permitted to go he would be first threatened, then fined, then cursed by the elders. Once inside the forest, its up to the morans to decide where they go.
Reasons for rules To ensure enough grass to last the dry season & because there were a lot of wildlife at that time when the forest was wet
Movement in forest was controlled to provide enough grass.
Cattle do not like the forest when the grass and segeet is too wet.
Segeet is the vernacular name for a group of grasses and herbaceous plants edible by cattle - see appendix
