Abstract

Listen

Integrating healthy, mature trees into paved urban environments is a challenging task for urban foresters, as impervious pavements are associated with reduced tree growth and survival. It is thought that porous pavements may alleviate this problem due to their permeability to air and water. The authors of the following study tested whether porous pavements affect tree growth relative to impervious pavements by measuring aboveground growth in trees treated with an augmented factorial arrangement of pavement profile designs and pavement types. Fifty oriental plane (Platanus orientalis) seedlings were evenly distributed to control plots or one of four treatments. Treated plots were characterized either by porous or impervious pavement pads measuring 2.3 m × 2.3 m, that were underlain either by fine sandy loam or a gravel base and compacted subgrade, reflecting two pavement profile designs. Results show stem height, diameter, and biomass increased as a result of porous pavements. Greater growth proffered by porous pavements was negated by profile designs including a compacted subgrade and gravel base. Finally, impervious pavements did not negatively influence tree growth, relative to control trees.

The urban forest is a major infrastructure element, providing environmental, economic, and social benefits. Healthy, mature trees improve air and water quality (Xiao et al. 1998; Heckel 2004), moderate extreme temperatures (Long-Sheng et al. 1993), reduce energy consumption (McPherson 1994), increase real estate values (Anton 2005), provide wildlife habitat (Dunster 1998), and provide intangible benefits including aesthetic and recreational amenities. Street trees planted alongside roads and sidewalks are a major component of the urban forest. Street trees are subject to environmental stresses, both biotic and abiotic, which fluctuate and interact to affect plant function and growth. Furthermore, anthropogenic stresses compound the natural environmental stresses already imposed on trees. Buildings and pavements render ground surfaces impervious; stormwater management systems divert water away from soil and into designated reservoirs; soils are compacted to meet engineering standards; and trees are often planted in confined growing spaces. The additive effect of these and other factors is that urban trees have comparably shorter life spans and reduced annual growth than their forest-based conspecifics (Quigley 2004).

One defining characteristic of the urban environment is impervious pavement. This infrastructure element is used for roads, parking lots, and sidewalks. It is pervasive, and in some cases covers more than 50% of land surfaces (Ferguson 2005). Trees surrounded by pavements have their growing environment altered; soil chemistry and physics are both modified by overlying pavements (Craul 1985; Macdonald et al. 1993; Jim 1997; Celestian and Martin 2004), as are a number of localized atmospheric factors, such as surface temperature and vapor pressure deficit (Kjelgren and Montague 1998). This has led to speculation that pavements cause decreased growth, premature decline, and death (Kjelgren and Clark 1994; Iakovoglou et al. 2001; Schröder 2008).

The pavement profile for a load-bearing pavement will include, from bottom to top, compacted parent material (hereafter referred to as a subgrade), a gravel base, and typically, an impervious surface course. In contrast, the pavement profile design for non-load-bearing pavements may include only a surface course installed over a compacted subgrade. Surface courses such as concrete or asphalt, combine a well-graded mix of aggregates and a binder to maximize density and limit permeability. An alternative pavement type precludes the inclusion of fine aggregate and thus, results in a porous pavement. In contrast to impervious pavements, porous paving is characterized by a matrix of interconnected pores, which render it permeable to air and water. Porous pavements are generally perceived to promote tree growth and survival by enhancing moisture infiltration and increasing soil aeration (Tennis et al. 2004; Ferguson 2005). Theoretically, this is plausible, but these hypotheses have never been experimentally tested in a system including live trees. In the following experiment, this gap in knowledge is addressed by testing the effects of porous and impervious pavement profile designs on tree height, diameter, and aboveground biomass.

METHODS

Listen

Study Site

The experiment was located at the city council nursery in Christchurch (Lat: −43.493, Long: 172.437), the largest city in New Zealand’s South Island. The top meter of soil is a fine sandy loam (Raeside 1974), and it overlies a deposit of sand and gravel, remnant from the alluvial outwash deposited by an ancient glacier (Brown and Weeber 1992).

The climate is temperate, and mean daily maximum temperatures range from c. 10°C in July to 21°C in January (McGann 1983). Occasional dry northwesterly winds occur during spring and summer, when temperatures can reach 30°C and relative humidity can drop to 20%–40% (McGann 1983). Rainfall ranges from 600–700 mm annually and is generally evenly distributed throughout the year, with a tendency for slightly higher early winter precipitation (McGann 1983).

Experimental Design

Chosen due to their wide-spread use as street trees, 50 one-year old, bare root oriental plane (Platanus orientalis) seedlings were randomly assigned to plots in an augmented factorial experiment consisting of controls and four treatments; trees were split evenly among treatments, such that ten replicates existed per treatment. Herbicide applications were used, as necessary, to limit weed competition in control plots, which were characterized by an exposed soil surface. In early August 2007, seedlings were planted at grade in undisturbed soil in plot centers and, in the case of treated trees, surrounded by concrete pavement pads, which had been installed in early July 2007. The pavement treatments, measuring 2.3 m × 2.3 m (with a 30 cm diameter circular cutout in the center), were based on the combination of pavement type (2 levels: porous, impervious) and pavement profile design (2 levels: +/− subgrade compaction and gravel base). The resulting four treatments were impervious concrete pavement (IP), impervious concrete pavement with compacted subgrade and gravel base (IP+), porous concrete pavement (PP), and porous concrete pavement with compacted subgrade and gravel base (PP+). The distinction between the two levels of pavement profile design is related to the preparation of the profile below the pavement surface course. In IP and PP plots, profile preparation was limited to leveling the topsoil with a 500 kg roller. In contrast, in IP+ and PP+ plots, topsoil was removed to a depth of 20 cm, exposing the parent material which was termed the subgrade. Then, a 20 cm deep base layer of washed, uniformly graded, 20–40 mm gravel was placed in the hole and leveled with a 500 kg roller. The difference between the two levels of pavement profile design are thus related to the inclusion (or exclusion) of a gravel base and the soil strength of the subgrade. Soil penetration resistance was measured via a soil compaction meter (Spectrum Technologies, Inc., Plainfield, IL, U.S.) in accordance with ASAE Standard EP542 (2002). Penetration resistance values for the uppermost 30 cm of soil are measured by a load sensor and displayed in kPa. Mean values differed significantly among treatments (P < 0.001) and were 892 kPa, 874 kPa, 808 kPa, 2458 kPa, and 2363 kPa for control, IP, PP, IP+ and PP+, respectively. Finally, IP and IP+ plots were overlaid by a standard impervious concrete, while PP and PP+ were overlaid by a pervious concrete designed specifically for this experiment.

Data Collection

Initial height and diameter were measured at the time of planting, in August 2007, prior to the first growing season; subsequent measurements occurred at the end of spring in the first growing season (December 2007), as well as the end of the first (March 2008) and second (March 2009) complete growing seasons. Tree height was measured as the distance between the soil surface and the tip of the apical bud on the leader of each tree, while the diameter was calculated as the average of two measurements taken perpendicular to one another 10 cm above the soil surface. Mean initial tree height was 62 cm and initial trunk diameter was 6.7 mm. Neither initial height (P = 0.663), nor diameter (P = 0.961) differed significantly among treatments. Height and diameter growth were measured as the absolute growth occurring over the duration of the experiment. On March 12, 2009, all trees were harvested at ground level. This plant material comprised aboveground biomass and was dried in a kiln at 70°C to constant weight (Nicholson 1984).

Statistical Analysis

One IP+ tree died between the first and second growing seasons and was thus excluded in all analyses. Stem height, diameter, and aboveground biomass were compared via one-way analysis of variance (ANOVA), using orthogonal, a priori, single degree-of-freedom contrasts to examine treatment effects, as well as interactions of interest (Marini 2003). Significant differences are reported for P < 0.05. Analyses were performed using the R statistical package, version 2.8.1 (R Development Core Team 2008).

RESULTS

Listen

Height Growth

While height growth was dependent upon treatment (P = 0.022), mean height growth of control trees was equivalent to all other treatments (Table 1, contrast 1), thus implying differences among the four pavement treatments. Alone, the pavement profile design had no effect on tree height, as the mean height growth of all PP and IP trees did not differ from all PP+ and IP+ trees (Table 1, contrast 2). Nevertheless, height was significantly affected by the interaction between pavement type and profile design (Table 1, contrast 4). Further investigation showed that without subgrade compaction or a gravel base, trees surrounded by porous paving grew approximately 205 cm, while those surrounded by impervious paving grew only 160 cm. However, in plots with a compacted subgrade and gravel base, a difference of less than 2 cm existed between trees surrounded by porous and impervious pavement (Figure 1).

Diameter Growth

Stem diameter growth was also dependent upon treatment (P < 0.001). Unlike height growth results, the mean diameter growth for all pavement treatments exceeded that for control trees (Table 1, contrast 1). While the effect of pavement profile design and pavement type were both significant, diameter growth depended on their interaction (Table 1, contrast 4). Diameter growth gains provided by porous pavement were limited to plots without a gravel base and subgrade compaction, as pavement type did not effect change in IP+ or PP+ plots (Figure 2).

Biomass

Aboveground biomass was dependent on treatment (P < 0.001) (Figure 3). Mean biomass for control trees was lower than the mean of treated trees (Table 1, contrast 1). While both pavement type and profile design main effects were significant, these factors exhibited a strong interaction (Table 1, contrast 4). Pavement type had no effect in plots with a compacted subgrade and gravel base, but trees in PP plots had significantly greater shoot biomass than trees in IP plots (Figure 3).

DISCUSSION

Listen

Within the context and limitations of this experiment, the results show: 1) impervious pavements alone do not restrict or compromise tree growth, relative to control plots; and 2) relative to control plots and impervious pavements, porous pavements can improve tree growth, but only in the absence of a compacted subgrade and gravel base.

Effect of Pavement on Tree Growth

It’s important to deconstruct pavements into their primary constituents, the pavement surface, and the underlying structural layers including a subbase, subgrade, and base. Many of the problems faced by street trees are generally ascribed to pavements without distinguishing between the surface or underlying structural layers. In the 1970s, it was commonly believed pavement surfaces caused reductions in soil moisture by precluding infiltration (Roberts 1977); however, more recent research has indicated that street trees may suffer from too much, rather than too little water (Berrang et al. 1985), though it’s unclear whether this is due to the surface or underlying soil compaction. Pavement surfaces have also been said to increase air (Whitlow and Bassuk 1988) and soil (Graves 1994; Celestian and Martin 2004) temperatures above levels for optimal physiological function. Furthermore, soil compaction beneath pavements has been linked to poor plant performance (Smiley et al. 2006). As pavements are associated with soil moisture extremes, excessive soil and air temperature, and root-limiting soil compaction, it is easy to understand why decline in street trees is ascribed to pavements.

In spite of this, none of the pavement treatments in this experiment negatively influenced tree growth relative to controls. In fact, tree height, diameter, and aboveground biomass were equivalent, or greater, in pavement-treated trees relative to control trees (Table 1, contrast 1). This suggests trees do not necessarily suffer from reduced growth and vigor as a direct result of overlying pavements. It is not disputed that street trees in paved areas are often associated with reduced growth rates and low survival, as this is well established (Gartner et al. 2002). However, pavements themselves are not necessarily the direct cause of tree decline. An alternative explanation is that street trees suffer from the compounding stresses often associated with pavements, such as restricted soil volume (Kopinga 1991), soil compaction (Philip and Azlin 2005), physical injuries to the stem and branches (Fostad and Pedersen 1997), air pollution (Su and Sun 2006), soil pollution via salt or other chemicals (Marosz and Nowak 2008), and soil moisture extremes (Berrang et al. 1985). These additional stresses were not measured in this experiment, except for soil compaction and soil moisture. The latter was measured as part of a larger experiment, and it was found that soil moisture beneath pavements consistently exceeded those in bare soil (Morgenroth and Buchan 2009). Given adequate soil moisture and the absence of many stresses known to afflict street trees, it is understandable why pavements alone produced no negative impacts on tree growth in this experiment.

Effect of Porous Pavement on Tree Growth

It has been suggested that porous pavements may play a role in improving tree growth by ameliorating underlying soil conditions (Ferguson 2005). This experiment confirmed tree growth can be improved by porous, rather than impervious pavement, but only in the absence of a compacted subgrade and a gravel base, where trees surrounded by porous pavements were taller and had greater stem diameter and aboveground biomass than trees surrounded by impervious pavement (Table 1, contrast 4).

It would be easy to suggest that differences in growth must be associated with the permeability of the porous pavement, and thus, higher soil moisture. However, Morgenroth and Buchan (2009) found that soil moisture did not differ beneath porous and impervious pavements. Therefore, other explanatory factors must be considered.

Knowing that increased growth occurred only in plots without a gravel base and compacted subgrade suggests that the benefits proffered by porous pavement are superseded by some factor associated with the profile design. One possibility is that soil compaction counteracted the effects of porous paving. Soil compaction is at odds with the requirements of trees, whereby highly compacted soils are known to negatively impact tree growth (Smith et al. 2001). In this experiment, soil penetration resistance in IP+ and PP+ plots was 2410 kPa. In contrast, soil in IP and PP plots had mean penetration resistance of only 841 kPa. In soils similar to those in this experiment, values between 2000 kPa and 3000 kPa are sufficient to hinder root development (Sinnett et al. 2008). Thus, it is likely the compacted subgrade restricted root development, thereby negating the positive effects of porous pavement exhibited in plots without a compacted subgrade and gravel base.

The theory that soil compaction negates the benefits provided by porous pavements could have critical implications for future porous pavement installations. The vast majority of pavements are designed to bear heavy loads and are thus underlain by highly compacted subgrade and base layers. Accordingly, the use of porous pavement for tree growth amelioration may be limited to areas such as sidewalks and low-use parking lots, unless steps are taken to minimize soil compaction. One way to minimize soil compaction is to use specially designed pavement profiles, whereby the pavements are engineered to withstand heavy loads, while avoiding soil compaction with the use of suspended pavements or accommodating compaction in soil design, such as with CU-Soil™. While these alternatives have been proven to perform as intended (Smiley et al. 2006; Buhler et al. 2007), their prevalence is presently restricted.

CONCLUSION

Listen

In summary, the present experiment revealed differences in tree growth resulting from differing pavement types and profile designs. Results indicate that pavements, in the absence of other stresses, do not cause reduced tree growth, even if the profile design includes a compacted subgrade and gravel base. It was also concluded that porous pavement could improve the aboveground growth of trees relative to those grown in impervious pavement settings. However, this was dependent on the absence of a gravel base and subgrade compaction. This research provided a glimpse into porous pavement’s effect on Platanus orientalis, a hardy species often planted as a street tree. More research is required to determine whether the results found here are applicable in varying climates or for different tree species planted in different soil types, and surrounded by various pavement widths and configurations, such as sidewalks, roads, or plazas. Given the increased installation of porous pavements in the urban environment, such future research would help explain the growth and survival of trees in the urban forest.
