Seeing the Wood for the Trees: Active human-environmental interactions in arid northwest China
Abstract. Due largely to demographic growth, agricultural populations during the Holocene became increasingly more impactful ecosystem engineers. Multidisciplinary research has revealed a deep history of human-environmental dynamics; however, these pre-modern anthropogenic ecosystem transformations and cultural adaptions are still poorly understood. Here, we synthesis anthracological data to explore the complex array of human-environmental interactions in the regions of the prehistoric Silk Road. Our results suggest that these ancient humans were not passively impacted by environmental change, but rather they culturally adapted to, and in turn altered, arid ecosystems. Underpinned by the establishment of complex agricultural systems on the western Loess Plateau, people may have started to manage chestnut trees, likely through conservation of economically significant species, as early as 4600 BP. Since ca. 3500 BP, with the appearance of high-yielding wheat/barley farming in Xinjiang and the Hexi Corridor, people appear to have been cultivating Prunus and Morus trees. We also argue that people were transporting the preferred coniferous woods over long distance to meet the need for fuel and timber. After 2500 BP, people in our study area were making conscious selections between wood types for craft production, and were also clearly cultivating a wide range of long-generation perennials, showing a remarkable traditional knowledge tied into the arid environment. At the same time, the data suggest that there was significant deforestation throughout the chronology of occupation, including a rapid decline of slow-growing spruce forests and riparian woodlands across the northwest China. The wood charcoal dataset is publicly available at https://doi.org/10.5281/zenodo.8158277 (Shen et al., 2023).

Reviewer’s comment
This manuscript reports human-environment interaction in northwestern China during the late Neolithic and Bronze Age. The study highlighted the impact of agriculture on human wood utilization in this area. On the whole, I believe that this manuscript has significant merit to warrant publication, in particular the amount of work done to reveal the history of human wood usage in northwestern China. However, there are still some issues with this manuscript, and should be revised. The major concerns are as follow:
Introduction:
I am uncertain what the exact question or hypothesis is of the authors. It seems to me like there was no clear expectation set forth at the beginning of the manuscript and that the authors just did a large-scale analysis with no clear plan. The question in this study is “Anthropogenic impact on environment” or “wood usage and its influencing factors” ? From line 120-122, it seems to discuss “wood usage and its influencing factors” ?
Discussion:
The author highlighted that anthropogenic impact on deforestation. However, has climate change also played the role? Because, the climate in northwestern China has become cold and dry since the late Neolithic. So if the deforestation was entirely caused by human wood collection, it should be ruled out the impact of climate change on woody vegetation, especially that of Spcure.
The pollen records in Fig 4 are from the archaeological sites? The captions of this figure should be more explained. If so, the similar changes in the records of charcoal and pollen do not indicate the woody degradation in northwestern China. Because pollen records from the section of archaeological site likely also show the trend of wood usage.

Introduction:

We will provide a clearer set of goals or hypotheses relating to this paper in the introduction. Specifically, we sought to test the assumption that humans in the deeper past were changing forest communities; we also wanted to better understand how human culture allowed for better adaptations to a dynamic ecology over time along the ancient Silk Road. In many other parts of the world, it has been shown that when humans began to cultivate crops and engage in agriculture, the magnitude and complexity of their environmental interactions increased immensely. Northwestern China is located in the core area of the ancient Silk Road, and people in this area were the first to experiment with agricultural systems that integrated crops from both West and East Asia, making it an ideal zone for studying the interaction between early farmers and their environments. Over the past decade, scholars working in this region have mainly focused their attention on the relationship between climate change and Neolithic cultural development. To a lesser extent, scholars have studied anthropogenic impacts on regional ecosystems. Meanwhile, relatively less attention has been paid to the cultural responses and adaption strategies employed by early farmers in these arid environments.
Discussion:
The author highlighted that anthropogenic impact on deforestation. However, has climate change also played the role? Because, the climate in northwestern China has become cold and dry since the late Neolithic. So if the deforestation was entirely caused by human wood collection, it should be ruled out the impact of climate change on woody vegetation, especially that of Spruce.
The reviewer is, of course, correct that we should rule out the impact of climate change on woody vegetation here. In fact, this one of the core dilemmas that paleoenvironmental work grapples with; differentiating anthropogenic and natural environmental changes in the past is not easy, and indeed, not always possible. That said, in this study, in order to figure out the temporal change of vegetation and its influencing factor(s), we focused on wood charcoal data from archaeological sites with continuous strata. Although we cannot totally differentiate between these factors, we can try to make correlations between paleoclimatic data and the archaeological record, for example:
Along the Tianshan mountains, wood charcoal data from Sidaogou (3400-3000 BP) recorded a significant decrease of spruce wood fragments, and Tamarix and Salix nearly disappeared in the later stage. Similarly, Tamarix charcoal from the Xintala (3900-3500 BP) section decreased to its lowest level in the upper layer, Populus and Salix charcoal disappeared in the middle layer. However, pollen records from Bosten and Balikun lakes showed a relatively stable climate during 3900-3500 BP, and a long-term increase of humidity after 3800 BP (Chen et al., 2006; Huang et al., 2009; An et al., 2012). Thus, we infer that the quick decrease in woody plants was resulted from anthropogenic exploration rather than climate change. Also, on the western Loess Plateau, the sudden disappearance of conifer trees after 4600 BP coincided with the appearance of wheat, barley and buckwheat in the Xishanping site, indicating intensive agriculture activities (Li et al., 2007). In the Majiayao section, the wood charcoal of Picea suddenly decreased from its highest level of nearly 40% to the lowest of less than 4% at around 5300-5100 BP. While, according to an analysis based on a high-resolution (~5 years) stalagmite sequence from the western Loess Plateau, there was no abrupt climate events during this time (Tan et al., 2020). In the Hexi Corridor, previous studies based on wood charcoal records also pointed to an anthropogenic impact rather than climatic change that caused a quick decline of riparian woodland and coniferous forest (Li et al., 2011; Shen et al., 2018). Collectively, we concluded that our wood charcoal revealed widespread deforestation starting with Neolithic agriculture.

The pollen records in Fig 4 are from the archaeological sites? The captions of this figure should be more explained. If so, the similar changes in the records of charcoal and pollen do not indicate the woody degradation in northwestern China. Because pollen records from the section of archaeological site likely also show the trend of wood usage.
Yes, the pollen diagrams in Fig 4 are from archaeological sites, while the strata contain both natural layers before humans became prominent in the area and cultural layers under human influence, as showed in Fig 4a (see the column chart on the left side). Therefore, the pollen records could provide clues to not only the initial natural vegetation but also the wood usage and vegetation variation during human settlement. In this study, the pollen records from Donghuishan, Majiayao, and Xishanping all show a relatively med-level abundance of Picea in natural layers before humans. With the beginning of human occupations, both wood charcoal and pollen content were relatively high, showing intensive collection of spruce wood, as the reviewer suggested. While afterwards, wood charcoal and pollen both decreased quickly, and the content of pollen is less than that in the natural layer, indicating the decline of spruce forest. At the later stages, people kept using spruce wood, while the pollen percentage remained low and almost disappeared in Donghuishan and Majiayao sites, suggesting that spruce forests around the sites were largely destroyed. Thus, we infer that the synchronous decline of wood charcoal and pollen in these sites suggested not only the pattern of wood usage, but also a quick deforestation process of spruce forest due to intensive human cutting.
We will also add more information to the figure caption, as the reviewer suggests.

We agree with the reviewer that it is difficult to identify wood charcoal into species level. According to Flora of Xinjiang (Editorial Committee of Flora of Xinjiang, 2011), two species, namely Elaeagnus angustifolia and Elaeagnus oxycarpa, are distributed in Xinjiang. Now, Elaeagnus oxycarpa is classified into Elaeagnus angustifolia (https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:70028324-1), suggesting that only the species of Elaeagnus angustifolia is native to Xinjiang. Thus, we think the wood charcoal from our study sites in Xinjiang should be Elaeagnus angustifolia. In order to make our readers unconfused about this part, we will change the identification result into Elaeagnus.
