Battle for our Birds

Many different species mast (including hinau, rimu, kahikatea, tussock, pigeonwood, beech) at varying times and can fuel rodent eruptions and other productivity

Oxford University Press, Melbourne. 610 pp.	Ship rat	“Heavy seedfalls of hinau…and pigeonwood … preceded both extended (winter) breeding by females and high spring rat density … in the Okarito kiwi sanctuary (10,000 ha) after good fruiting seasons for rimu in winter 2002 and kahikatea in 2003, ship rat populations erupted.”

Ecosphere 5(4): 1-14	Spatial and temporal variation in tree seed production and dispersal in a New Zealand temperate rainforest	“The four species differed widely in both the frequency of large seed crops and the duration of intervals between years of high fecundity. Silver beech showed a consistent pattern of alternating years of low versus high fecundity (Fig. 2C). Mountain beech, in contrast, had one year (2009) with very high fecundity following a year (2008) with an almost complete seed crop failure, but the preceding six years were characterized by variable but low to moderate fecundity (Fig. 2C). Hall’s totara showed a cyclical pattern with a five-year interval between years of very low fecundity (2002 and 2007), but the intervening years were characterized by very gradual inter-annual increases and then decreases (Fig. 2c). Rimu was characterized by two years of high fecundity (2002-2003), followed by five years of low to moderate fecundity (Fig. 2C).”
2014	Canham, C.D., Ruscoe, W.A., Wright, E.F. & Wilson, D.J.	Ecosphere 5(4): 1-14	Spatial and temporal variation in tree seed production and dispersal in a New Zealand temperate rainforest	“In contrast to expectations from classic masting theory, the mixed species forests [in the Southern South Island] we studied showed little temporal synchrony in seed production across tree species …results suggest that these mixed podocarp/angiosperm forests will have very different spatial and temporal dynamics of introduced mammals than simpler forests dominated by one or a few tree species.”

NZ Journal of Ecology 36(2): 131-140	Quantifying the benefits of long-term integrated pest control for forest bird populations in a New Zealand temperate rainforest	“We suggest that correlations between mōhua, rifleman and yellow-crowned parakeet may have resulted from peak breeding in both species occurring simultaneously following heavy seedfall (Elliot et al. 1996).”
