Effects of different grasses on ponderosa pine seedling establishment
Frank J. Baron
Ponderosa pine and eight grass species were planted together on a burned area. Less than half the pine were dead after 3 years, whether in grass areas or not. When pine was planted in year-old grass, 80 percent died. Of pines planted without grass, only 30 percent died. Grass species differed in their effect on tree survival.

Smoke-cued seed germination and emergence is common in some frequent-fire ecosystems, but this process is little studied in frequent-fire conifer forests of the southwestern United States. To assess whether aqueous smoke promotes plant emergence in frequent-fire ponderosa pine (Pinus ponderosa) forests in northern Arizona, I conducted three experiments at different Cited by: Effects Of Prescribed Fire In Mixed Conifer Forest, Crater Lake National Park, Oregon by Ronald J. and Joy D.

Baron ABSTRACT: Ponderosa pine and eight grass species were planted together on a burned area. Less than half the pines vere dead after 3 years, whether in grass areas or not.
When pine was planted in year-old grass, 80 percent died. Of pines planted. summer, each seedling was watered by hand twice in June to reduce mor-tality. No other supplemental watering occurred. Six potential competitors of ponderosa pine seedlings were chosen for this study, including four grasses and two forbs.
The grasses included: (1) Bouteloua grucilis (H.B.K.) Lag ex Steud. (blue grama), (2) Ductylis glo-Cited by: Nitrate and ammonium concentrations in various grass treatment plots were significantly (P) different at both the beginning and end of the growing season.
Pine seedling xylem water potential differed among treatments, with potentials being lowest on plots sown with Agropyron desertorum. The differences in seedling xylem water potential and available soil nitrogen were reflected in differences in pine seedling by: Remove original litter, plant grass seed, remove new needle fall each spring.

The four treatments were two broadcast applications, a single broadcast application, a large spot application, and a small spot application. Seedling survival and growth were monitored for five growing by: 8.
In a study on the effect of year-long grazing on longleaf pine (Pinus palustris Mill.) in Alabama, Boyer () found that even light grazing caused a seedling mortality rate of 23 percent after the first year.
McClean and Clark () found damage to heavily stocked stands of lodgepole pine (Pinus contorta by: 1. Soil surface conditions can have profound effects on plant seedling emergence and subsequent seedling survival. To test the hypothesis that different soil-surface treatments with logging residue affect range grass seedling emergence and survival, 6 alternative forest-residual treatments were established in the summer of following thinning of mature trees from Cited by: 9.
Successful ponderosa pine seedling germination and establish- ment generally requires a large supply of seed, a mineral seedbed, sufficient moisture, reduced unders- tory cover, and light (Larson and Schubert, ;Schubert, ;White and Pickett, ;Kolb and Robberecht, ;Stein and Kimberling, ).
Three ponderosa pine (Pinus ponderosa Lawson & C. Lawson var. ponderosa C. Lawson) seedling stock types were planted in the field and subjected to three levels of competition.

and Klamath Mountains ecoregions, ponderosa pine woodlands have open canopies, generally covering percent of the sky. Their understories are variable combinations of shrubs, herbaceous plants, and grasses. Ponderosa woodlands are dominated by ponderosa pine, but may also have lodgepole, western juniper, aspen, western larch.
Alternatively, purchase a young ponderosa pine from your garden store. Ponderosa pine care is easier if you plant the tree in a sunny location on loamy, well-drained soil. Don’t neglect water in the period of establishment when you are growing.
Establishment. Ponderosa pine establishes well given proper site conditions and preparation. Control of rhizomatous grasses and forbs 1 to 2 years prior to planting is highly recommended, as is the use of high quality woven weed fabric.

Ponderosa pine (Pinus ponderosa Laws) is able to compete with grasses if planted before or at the same time as grass, but the degree of competition depends upon the species of grass (Baron, ).
However, both root and top growth of ponderosa pine seedlings is significantly greater when grown in. modeling; seedling establishment (seedlings/m 2, data from White and Mast et al. ) for frequent-fire modeling.
Mortality risk for ponderosa pine from fire was calculated using data for “light surface fires” and “hot surface fires” from Lindenmuth (). Multiple runs of FIRESUM were made in two differ-ent ways. The more rapid decline in cover of seeded species on the fire sites was due to rapid establishment of lodgepole pine on the Canyon Creek fire sites.
Erosion. On the fire impacted sites, the average cover factor for the seeded sites was 61% of the controls indicating erosion was decreased by at least 39% (Fig. bunch grass and pine grass (USDA, ARS, NGRP, ). Uses: Grazing/Rangeland: lived perennial bunch grass.

The seedlings, grown from seed collected locally, were planted with l-m spaces between trees. Six bitterbrush seedlings per plot were planted along with the pine seedlings. The bitterbrush seedlings were 10 to 15 cm tall when transplanted.
The first objective of this paper was to assess the effects of grazing on seedling establishment of two species whose relative abundance at the adult stage is affected by grazing in a contrasting fashion.
Second, we evaluated the relative importance of seed versus safe‐site availability in explaining the effect of grazing on seedling Cited by: Pine needles are a good choice for mulching, and really economical if you have pine trees in your yard or pine straw easily available locally.
Because pine needles break down so slowly they are not good additives to turn directly into garden soils. Prescribed fire is a widely applied tool for lowering future wildfire severity in western US ponderosa pine (Pinus ponderosa Lawson & C.

Bags will be constructed from mm mesh to allow arthropod detritivores access to the litter. In order to test the relative effects of substrate quality versus microclimate on litter decomposition rates, we will fill half the litterbags with 2 g of ponderosa pine needle litter, and half with 2 g of senesced grass and forb material.
The foreground at this location shows a plant grouping which includes evergreen trees and grasses and shrubs consistent with an intact ponderosa pine plant community. The rock outcrop in the median is high enough to block views of the southbound lanes. The outcrop is dramatic and higher in elevation than the roadway adding interest to the view.

[from the text] This paper synthesizes information regarding the effects of fire on soils in southwestern ponderosa pine. The intended audience for this paper is managers and others interested in ponderosa pine fire management in the Southwest.
Where specific studies of fire effects on some soil properties in the Southwest are lacking, we have drawn inferences .Dendrochronological techniques were used to assess the effect of fire exclusion on the radial growth of two age classes (approximately and years old) of mature ponderosa pine.
Decline in average radial growth in both classes is coincidental with the establishment of a large ponderosa pine seedling crop in that has since become.Ponderosa and Jeffrey pine sapwood samples and freshly cut stumps from trees with different amounts of oxidant injury were inoculated with Fomes annosus.
With stumps, percentage of surface cross-section area infected and extent of vertical colonization were determined 1 mo and mo after inoculation, respectively.
