Leaf area index change in ice-storm-damaged sugar maple stands

Abstract: Changes in Leaf Area Index (LAI) between the summers of 1999 and 2000 were measured using the TRAC optical instrument in sugar maple stands damaged by the 1998 ice storm. Changes were determined to be significant if they were greater than the 95% bounds of the instrument precision. They were evaluated in relation to 1998 canopy damage estimates, 1999 stand treatments (lime, fertilizer, lime + fertilizer, herbicide, none), and 1999 understory vegetation cover. Results show that LA1 change is significantly relat… Show more

“…However, poststorm measurements of canopy features were strongly correlated with initial crown damage estimates in all three growing seasons (Table 4). These results and those of Olthoff et al (2001) suggest that single-date measures of post-disturbance LAI, gap fraction and percent overstory canopy cover provided fairly reliable estimates of residual ice damage and canopy recovery in a given growing season.…”

“…As with other non-destructive approaches, the indirect LAI estimates provided by the TRAC may underestimate the true LAI, and are often referred to as "effective LAI." However, this instrument has been found to provide reliable estimates of LAI comparable in accuracy to other commonly used methods and instruments (Olthoff et al 2001). The instrument was held ~ 1.5 m above the forest floor during its operation and therefore provides LAI and gap fraction values for the overstory and that portion of the understory canopy ≥ 1.5 m height.…”

“…It is important to note that this broad level survey was not intended to provide a high resolution inventory of the damage, but rather to provide a rapid delineation and description of the damage to be used as a planning tool for research programs (Lautenschlager and Nielsen 1999). Ground-based research plots (e.g., Hopkin et al 2001, Lautenschlager and Winters 2001, Manion et al 2001, Olthof et al 2001, Ryall and Smith 2001 or more intensive stand level assessments were still conducted to further quantify the damage and to make management decisions specific to a site or woodlot.…”

“…Near-ground deciduous tree species, herbaceous species, and total vegetation cover all increased with increasing severity of ice damage to the canopy, while fern coverage decreased slightly with increasing damage. The response by these groups is most likely related to the combined increase in sunlight reaching the forest floor (Olthof et al 2001) and increased moisture and nutrient, most likely nitrogen, availability. However, significant interaction terms provided some evidence that these changes may be short-lived.…”
