These typically grow faster than upland species like red oak (Quercus rubra) and sugar maple (Acer saccharum). The idea that the greater trait plasticity of Norway maple in response to environmental conditions could account for its invasive ability (Martin et al. But the reason it got its name is because the tree starts to take on a scarlet tinge in late winter as its red flower buds (yes, maples have flowers) develop, followed by red stems for the leaves. 2004, Campos and Herrera 2009) and in other locations throughout Europe (see status reports on DAISIE; www.europe-aliens.org). Those ideas, as well as that of phylogenetic distance (above), cannot however explain the results found here where enemies of both maple species were controlled. Another advantage that helps Norway maples outcompete its plant neighbors but also endears it to me, is that it blooms and leafs out early. The soil surface was covered with 2.5 cm of extruded polystyrene foam and a white plastic sheet for insulation and protection from rodents.

Norway maples produce huge seed crops, much greater than sugar maples, and their seeds, carried by the wind, tend move into maple forests where they grow readily. It was brought to North America in the mid-1700s as a shade tree. Norway maple (Acer platanoides) has made its own place in the culture and is a common shade tree that resembles sugar maples. Seed Set . An average height is 10 to 15 feet in 15 years of growth, with much of their growth coming in earlier years. Average Growth Rate: 3 Feet Per Year: Mature Size: 45 Tall x 35 Wide: Light Needs: Full sun: Decidious or Evergreen: Deciduous: Acorns: No it doesn't have acorns: Color: Rich green foliage which turns red in the Fall. Thus, the lower root : shoot ratio in Norway maple would confer a productivity advantage consistent with its greater invasiveness following canopy disturbance. Statistical analyses were carried out using JMP 8 (SAS Institute Inc., Cary, NC, USA). April 15, 2020. A previous pot experiment confirmed that such homogeneous conditions are not an ideal proxy for forest understories and led to overestimation of Norway maple seedling growth and carbon gain (Paquette et al. Growth in second-growth stands, however, generally exceeds 5.1 cm (2 in) in 10 years for saw-log-size trees (18) and a maximum rate in excess of 10.2 cm (4 in) has been reported (106). 2007a). Also, when the stem is broken, the sap from the royal red maple tree is milky, not clear. In eastern and central North America, Norway maple (Acer platanoides L.) has become invasive in some deciduous forest understoreys where sugar maple (Acer saccharum Marsh) and associated species normally dominate forest regeneration (Webb et al. Height growth relative to time (Julian days—seasons and dates also provided for reference). The hypothesis was tested on the same pair of maple species with mixed results, Cincotta et al. Norway maple’s large, leafy canopy shades out other plants and, due to its root structure, no other plants can grow below it. Quebec's Ministère des Ressources naturelles et de la Faune provided both seeds and helpful advice for the production of sugar maple seedlings for this experiment. We wish to thank the Montreal Botanical Garden for providing the space necessary for this experiment.

Effect of light regime treatment and species on diameter growth (D), biomass (W) partitioning, physiological response (Amax) and relative growth rates (RGR), as assessed by REML analysis (P values for each effect and R2 for the whole model are provided). The oval to rounded crown fills with maroon-yellow flowers in the spring. Growth Rate. Different varieties of maple have different life spans, but most grow to be more than 100 years old. 2003, Valladares and Niinemets 2008). It has a low canopy with a typical clearance of 5 feet from the ground, and should not be planted underneath power lines. 2011b). Shade-houses had roof openings calibrated to provide different daily and seasonal amounts of direct-beam insolation in the gap and understorey light regimes, respectively (Paquette et al. Current Norway GDP Growth Rate is 1.09%. Suzan Bellincampi is director of the Felix Neck Wildlife Sanctuary in Edgartown, and author of Martha’s Vineyard: A Field Guide to Island Nature. Thus, in contradiction to our main hypothesis, Norway maple actually outperforms or at least matches sugar maple growth and production potential under both understorey and gap light regimes. We also observed a higher level of maximum photosynthesis in Norway than in sugar maple under both light regimes, which is consistent with other reports (Kloeppel and Abrams 1995, Reinhart et al. Some trees are slow growers (20-30 years to reach full size) and some are fast (10-15 years).

Using the data provided in their Appendix (n = 40 per species and light regime), we computed a phenotypic PI for Amax. This idea is consistent with two meta-analyses showing increased adaptability to changing conditions in invasive species compared with native congeners, especially when going from average to high resource availability (Daehler 2003, Davidson et al. Although the difference between species was less important than in gaps (47%), maximum photosynthesis was also 13% higher for Norway maple under understorey low-light conditions than for sugar maple. Reproductive Age . These wood-frame shade-houses were erected at the Montreal Botanical Garden (+45°33.7′; −073°34.3′) in a split-plot design comprised of four blocks and two relative light intensities (understorey and gap, see below), with each treatment assigned at random within its block. All rights reserved. The silver maple grows to a height of 50–80' and a spread of 35–50' at maturity. According to the Arbor Day Foundation, slow growth designates a tree that grows less than 12 inches per year, while medium denotes growth of between 13 and 24 inches annually. Top 10 Trees for a Small Yard. The maximum photosynthetic capacity under saturating light (Amax) was measured using a LI-6400 portable photosynthesis system fitted with a red–blue light source and CO2 injector (LiCor, Lincoln, NE, USA). In particular, exploitation of temporal variation in light intensity caused by canopy gaps can be important in explaining the success of maple species in forests (Canham 1988, Lei and Lechowicz 1997, Paquette et al. Acer platanoides, commonly known as the Norway maple, is a species of maple native to eastern and central Europe and western Asia, from France east to Russia, north to southern Scandinavia and southeast to northern Iran. Norway Maple, Acer platanoides. September . trees to 2.6 in.2/year in 18-in. Furthermore, the capacity of Norway maple to take advantage of favourable conditions in fall, which may come at the cost of increased early frost damage, as well as its superior plasticity in response to forest disturbance, may well increase the invasiveness of Norway maple as global change leads to increased growing season length and variability in climate (Schwartz et al.
