“…The raw material for the Swedish-Finnish pine tar production of the 17th and 18th centuries consisted mainly of resin-soaked stems from relatively young pine trees. This can be accomplished by debarking the pine trees during a period of three to four years in order to accelerate the lightwood formation of the trees [19]. The use of young pine trees was as a result of the increasing demand for pine tar, and the peasants, who performed the burning, were either too impatient or too poor to wait for the stumps to mature naturally [36].…”

“…For girdling, the depth of the wound and, more importantly the nature of the destroyed and damaged tissues (bark, cambium, phloem, and/or xylem), determines the potential for recovery and the effectiveness of the phloem transport disruption. In forestry, girdling is often performed using chainsaws or axes to kill trees (Bauhus et al, 2009) or induce desired wood properties (Gref and Ståhl, 1994;Taylor and Cooper, 2002). With such crude methods, the functioning xylem is generally damaged (see Figure 2B).…”

Carbon dynamics within trees are intrinsically important for physiological functioning, in particular growth and survival, as well as ecological interactions on multiple timescales. Thus, these internal dynamics play a key role in the global carbon cycle by determining the residence time of carbon in forests via allocation to different tissues and pools, such as leaves, wood, storage, and exudates. Despite the importance of tree internal carbon dynamics, our understanding of how carbon is used in trees, once assimilated, has major gaps. The primary tissue that transports carbon from sources to sinks within a tree is the phloem. Therefore, direct phloem transport manipulation techniques have the potential to improve understanding of numerous aspects of internal carbon dynamics. These include relationships between carbon assimilation, nonstructural carbon availability, respiration for growth and tissue maintenance, allocation to, and remobilization from, storage reserves, and long-term sequestration in lignified structural tissues. This review aims to: (1) introduce the topic of direct phloem transport manipulations, (2) describe the three most common methods of direct phloem transport manipulation and review their mechanisms, namely (i) girdling, (ii) compression and (iii) chilling; (3) summarize the known impacts of these manipulations on carbon dynamics and use in forest trees; (4) discuss potential collateral effects and compare the methods; and finally (5) highlight outstanding key questions that relate to tree carbon dynamics and use, and propose ways to address them using direct phloem transport manipulation.
