The Impact

Abstract The translation of genetic gains into economic gains is important for evaluating the impact of using genetically improved forest reproductive material (FRM) in the forest sector. However, few studies based on European forests have been published to date. Here, we analyse the stand-level wood production and financial performance of planting genetically improved FRM in even-aged planted forests focusing on four European case studies with advanced breeding programme material and different management contexts: Scots pine (Pinus sylvestris L.) in southern Finland, central Sweden and central France, and maritime pine (Pinus pinaster Ait.) in southwestern France. The growth of improved stands was simulated using species-specific growth models by incorporating two levels of expected genetic gains (present and next generations of seed orchards, varying from 7 to 40 per cent depending on the breeding programme) into the estimated mean annual volume increment over a rotation (m3 ha−1 yr−1). For each level of genetic gain, we tested the plantation of improved FRM managed with two silvicultural scenarios (maintaining the standard baseline rotation and thinning regime vs shorter rotation through the earlier achievement of the recommended felling criteria) in comparison with the plantation of the reference unimproved material (absence of genetic gain) managed according to the standard silvicultural regime. The use of improved FRM resulted in a larger financial performance in terms of soil expectation value (SEV € ha−1, discount rate 3 per cent) than planting unimproved reference material in all case studies and silvicultural scenarios for different wood price contexts (SEV gain from +20 to +190 per cent depending on the genetic and silvicultural context). The challenges associated with the economic assessment of realized gains from genetically improved FRM are discussed. We argue that silvicultural guidelines should be adapted to the use of improved FRM in order to gain better financial performance and flexible silvicultural response of planted forests to future environmental and socio-economic changes.

The Impact

Although failure to account for spatial autocorrelation has been dramatic in some forest progeny trials, little attention has been paid to how this issue may affect selections within the trials. The effects of spatial autocorrelation of height growth on the estimation of genetic gain and on the spatial distribution of the selected trees were studied in four Pinus pinaster Ait. progeny trials that were rogued using different selection methods and intensities. When selections are based on unadjusted original values, selected trees tend to be located in the best microsites and are unlikely to be the most genetically superior. This resulted in a loss of genetic gain that varied between 10% and 20% and sometimes exceeded 30%. Differences in the loss of gain among different selection methods and intensities were minor and followed no clear pattern. Selecting on the basis of a conventional model resulted in spatial patterns of the retained trees that were clearly aggregated in all cases. However, selections based on spatially adjusted data resulted in random spatial patterns, except with family selection because of the use of multiple-tree plots. Because clumping of the retained trees may seriously affect the quantity and quality of the seed crop, breeders are strongly encouraged to use appropriate spatial models for roguing breeding seedling orchards.

The Impact

Genetically improved material has been proven to financially outperform unimproved material in timber production according to various studies. Genetic improvements in carbon sequestration are also promising, implying a possibility for further financial gains. Research Highlights: Including carbon pricing (i.e., timber production combined with carbon sequestration) with genetically improved material improves financial performance compared to pure timber production. Furthermore, the proportion of carbon benefit (%) of absolute bare land value fluctuates between 27% and 42%, indicating a substantial role of carbon sequestration to financial performance. Background and Objectives: Until now, economic analyses of the impact of tree improvement have mainly dealt with growth performance: volume yield or height growth. Yet planted forests can have a significant contribution to carbon sequestration, which will play a major role in carbon markets. This study focuses on comparing the financial performance between genetically improved and unimproved reforestation material when stand management is optimized according to timber production or to joint production (timber and carbon sequestration together). Another goal is to reveal possible differences in financial performance related to climatic conditions along the south–north gradient. Materials and Methods: The stand projections are based on simulations with and without genetic gains for joint production (timber + carbon) and merely timber production in eight locations in Finland. Stand-level optimization is applied for financial analyses. Results: Genetically improved reforestation material considerably enhanced financial performance when the joint production of timber and carbon was applied, regardless of the climatic region. Conclusions: If carbon pricing became a reality, there would be a distinctive shift in bare land values, which is further boosted by a genetic gain.

La mayoría de estudios sobre los efectos positivos de la mezcla de árboles en el contexto de suministro de servicios ecosistémicos (SE) se centran en mezclas que combinan especies diferentes. Sin embargo, este efecto es poco conocido cuando se mezclan especies del mismo género. Por ello, evaluamos el efecto de la mezcla sobre el suministro de SE en seis tripletes [6 tripletes×3 rodales (2 rodales puros+1 rodal mixto) =18 parcelas) de pino albar (Pinus sylvestris L.) y pino resinero (P. pinaster Ait.) en el noroeste de España. En cada parcela, el suelo (una calicata de 50cm de profundidad), el sotobosque (diez inventarios de 1x1m) y el estrato arbóreo (a dos escalas espaciales; escala de vecindario: diez inventarios de 4m de radio/parcela; escala de rodal: un inventario de 15m de radio/parcela) fueron analizados. Los resultados de esta tesis contribuyen a comprender los mecanismos involucrados en el suministro de SE en rodales puros vs. mixtos de P. sylvestris y P. pinaster: las masas mixtas presentan una ventaja competitiva sobre los rodales puros en términos de conservación de la biodiversidad, secuestro de carbono, fertilidad edáfica y producción del estrato arbóreo. Teniendo en cuenta que estas mezclas están ampliamente distribuidas en España, parece oportuno proponer que se sigan promoviendo ya contribuyen a incrementar la fertilidad del suelo, la acumulación de carbono, a proporcionar un exceso de área basal en relación con masas puras, y a conservar la regeneración de especies endémicas y mantenimiento de la riqueza del sotobosque en suelos con menor contenido hídrico.
