Holmgren's interest in recombinant ecosystems or 'weedscapes' is partly inspired by a 1979 visit to New Zealand and interactions with New Zealand ecologist Haikai Tane (1995).
Holmgren'in rekombinant ekosistemler ya da 'weedscapes'lere olan ilgisi kısmen Yeni Zelanda seyahati (1979) ve Yeni Zelandalı ekolojist Haikai Tane (1995) ile etkileşimlerinden esinlenmiştir.
