  1. Heavy fruiting in Coprosma - anyone else noticing this?

    More out of interest than anything else - since February I have been observing some absolutely spectacular fruiting in Coprosma species. For me first noted in the Eastern Wairarapa where I and colleagues were impressed with the spectacular fruiting displays of Coprosma rigida, C. pedicellata and C. propinqua, and then yesterday on Mt Te Aroha C. grandifolia (see image). Similarly C. robusta, C. repens and C. spathulata subsp. spathulata are going for it around Auckland. Is anyone else seeing this in their rohe?

    Noted in coprosma but in a number of other species as well. Corokia cotoneaster, Pennantia corymbosa, Nestegis sps, Lophomyrtus obcordata and Myrsine divaricata. Wairarapa and around Gore and points further south as well

    Hi Peter, I've noticed it periodically in some years. Nothing out of the ordinary down here fruit-wise. FYI - I posited massed fruit displays may be an adaption to attract browsing by moa (and other frugivores). See Thorsen et al. 2011. Faunal influences on NZ seed dispersal characteristics. Evol. Ecol. 25: 1397-1426

    Kahikatea are LADEN around the Waikato!

    Yes in the Waitakere Ranges Coprosma grandifolia is bending under the weight of fruit.
    As are some Kahikatea and Rimu.
    For the Rimu I weighed the collected seed fall and estimate I got 1 kilo per square metre. But that was after a similar volume had already fallen and there were still heaps on the tree. Therefore 3 kilos per sq metre is an informed estimate with a tree having a 7x7metre coverage that totals 150 kilo per tree. Are there comparable records from other years/places?

    I have always noticed the LACK of fruiting in Coprosma dumosa. Finally I see it laden with fruit of every colour morph imaginable! (well, almost).
