Abstract

This data set reports tree growth measurements of mature Picea mariana and Larix laricina located in the S1-Bog permanent plots and the SPRUCE experimental study plots. Data have been collected annually from 2011 to 2024 (2011-02-23 to 2024-02-26) in late February/ early March to capture the productivity of the previous growing season (i.e. the February 2024 measurements track the 2023 growing season). Data collections are anticipated to continue through February of 2026 and this data set will be appended annually. Initial observations in 2011 included measurements of circumference at 1.3 m (diameter at breast height assessments; DBH) above the nominal bog hollow surface, tree heights and crown diameters. Subsequent annual measurements have focused on the measures of circumference at DBH. Supplemental tree height data collected via terrestrial lidar (Graham et al. 2019) were initiated in 2016 and have been maintained annually. Circumference measurements to the nearest 0.1 cm are converted to DBH in cm and basal area at DBH in (cm2). Tree height and crown diameter are measured to the nearest 0.1 m. This dataset contains one data file in comma separate (*.csv) format. User Note: In this Version 2, some previously released ‘Circum_Status’ values were updated to fix misreadmore »« less

SPRUCE Shrub-Layer Growth Assessments in S1-Bog Plots and SPRUCE Experimental Plots beginning in 2010

Dataset Hanson, Paul J. ; Birkebak, Joshua M. ; Phillips, Jana R. ; ...

This data set reports shrub layer growth assessments for the S1-Bog on the Marcell Experimental Forest in Minnesota from 2010 through 2023 (2010-08-01 to 2023-08-31, no data were collected in 2020 and 2022). Data were obtained by destructively harvesting selected plots of varying number and size. In early years a distinct hummock and a hollow sampling square were both collected, but in later years unsampled hollow areas became unavailable due to prior sampling or instrument installations. Harvested samples were broken down species, tissue type (leaf or stem/), and by whether tissue was from the current year’s growth or growth frommore »« less
SPRUCE Photosynthesis and Respiration of Picea mariana and Larix laricina in SPRUCE Experimental Plots, 2019

Dataset Balog, Madeline E. ; Hauger, Jacob ; McLennan, David A. ; ...

This data set contains physiological, morphological, and chemical measurements of the two dominant coniferous species, Picea mariana and Larix laricina, in August 2019 (2019-08-20 to 2019-08-22) at the SPRUCE (Spruce and Peatland Responses under Changing Environments) experiment site in the Marcell Experimental Forest in northern Minnesota, USA. These observations help to assess the effects of whole ecosystem scale warming and elevated CO2 concentrations on peatland ecosystems. Measurements include light-saturated photosynthesis and foliar dark respiration measurements under standard conditions and growth conditions involving varying temperatures and atmospheric CO2 concentrations, as well as leaf morphology measurements (leaf mass per unit leaf area)more »« less
SPRUCE S1 Bog Seasonal Patterns of Nonstructural Carbohydrates in Larix, Picea, Rhododendron, and Chamaedaphne, 2013

Dataset Furze, Morgan E. ; Jensen, Anna M. ; Warren, Jeffrey M. ; ...

These data report the results of nonstructural carbohydrate (NSC) analyses of foliage/twig/root tissues collected at the SPRUCE site in 2013. Samples were obtained at various locations around the S1 Bog. These are pretreatment vegetation samples, collected prior to initiation of the SPRUCE experiment heating and elevated CO2 treatments.
SPRUCE Photosynthesis and Respiration of Picea mariana and Larix laricina in SPRUCE Experimental Plots, 2016-2017

Dataset Dusenge, Mirindi Eric ; Ward, E.J. ; Warren, J.M. ; ...

This data set contains empirical physiological, morphological, and chemical data collected on two dominant conifer species, Picea mariana and Larix laricina, between May 2016 and August 2017 at the SPRUCE (Spruce and Peatland Responses Under Changing Environments) experiment that assesses the response of peatland ecosystems to whole-ecosystem warming and elevated atmospheric CO2 concentrations. Data reported include: measurements of light-saturated net photosynthesis and dark respiration at ambient atmospheric CO2 concentration (2016), CO2 response curves of light-saturated net photosynthesis (2017), leaf morphology (leaf mass per unit leaf area), and nitrogen content (on both mass and area basis).

SPRUCE Diurnal and Seasonal Patterns of Water Potential in S1 Bog and SPRUCE Experimental Plot Vegetation beginning in 2010

Dataset Warren, Jeffery M. ; Peters, Jen M.R. ; Childs, Joanne ; ...

This data set reports on water potential from excised terminal shoots or leaves (Mainthemum only) of vegetation at the SPRUCE site located in the S1 bog. Pretreatment measurements were collected from outside plots within the S1 bog. Post treatments were collected from inside SPRUCE plots. Water potential was measured on the overstory canopy species, consisting of the evergreen Picea mariana (Mill.) B.S.P. (black spruce) and deciduous Larix laricina (Du Roi) K. Koch (tamarack) trees, and ericaceous shrubs < 1 m tall, consisting of the evergreen Rhododendron groenlandicum (Oeder) Kron & Judd (Labrador tea) and Chamaedaphne calyculata (L.) Moench. (leatherleaf). Somemore »« less
