Tree-rings and transportation in the New Zealand kauri (Agathis australis) timber industry: Investigating the time lag from tree to building

Provenancing kauri: Reconstructing the supply of kauri timber into Auckland city, 1850–1889

“…Using the spatial divisions, the percentage of arrivals of timber‐carrying vessels and load quantity from each region were calculated for 5‐year slices between 1 January 1850 and 31 December 1889. Aggregating data into 5‐year slices both maintained manageability of the data set and allowed for time lags between trees being felled and milled, shipping of timber, and use in structures (see Boswijk, Munro, & Jones, 2014). The arrival data for each sub‐region were further subdivided into broad catchments to build a picture of the spatial and temporal expansion and contraction of sawmilling in the kauri region, and the persistence and dominance of particular production catchments as sources of timber despatched inwards to Auckland (Table 2).…”
