Ramets in the most recently burned patches in PBG pastures had 2.6 times more stems, and ramets in GAB pastures the year it was burned had 2.2 times more stems than pastures not burned in over 3 years.
From 2011 to 2013, we measured how S. orbiculatus basal resprouting and layering stems were affected by patchy fires on grazed pastures, complete pasture fires on grazed pastures or fire exclusion without grazing for more than three years.
The number of stems per ramet on burned pastures, regardless of how fire was applied, was significantly higher (F2,66 = 6.39; P < 0.01) than pastures not burned in over 3 years (Figure 2C).
The meadow rue has been growing taller than usual; buttercups were spread high across the pasture; Queen Anne's lace unfurled its white parasols on stems that seemed perilously long.
New layering stems were only identified in 2011 and 2013 in the PBG pastures and in unburned pastures in 2011 only (Table 1). Figure 1 Diagram of fire effects measurements given the clonal nature of S. orbiculatus.
Applied to traditional management, erashe describes the stems deliberately left ungrazed after livestock are introduced on a pasture.
Pastures not burned in over 3 years had no new layering stems (P < 0.01) (Figure 3A).
The absence of cattle grazing activity as a source of physical disturbance in the unburned pastures could also help explain the lack of new S. orbiculatus layering stems (Abrahamson [1975]).
In Tanzania, the vast majority of fire events stem from anthropogenic ignitions for different purposes, including farm preparation, pasture management, hunting, honey harvesting, charcoal production, arsons, and for security around settlements and roads [35].

The town has a long association with cattle, even in its name which is said to stem from an Anglicisation of the Welsh Buallt - which roughly translates as ox pasture.
