1. What is Tree Spacing Calculation?

The tree spacing calculation determines how many trees can be planted per hectare based on the spacing between rows and between trees within a row. This is crucial for optimal growth and resource utilization in forestry and orchard management.

2. How Does the Calculator Work?

The calculator uses the standard tree spacing formula:

Where:

• Row spacing — Distance between rows of trees (meters)
• Tree spacing — Distance between trees within a row (meters)
• 10000 — Number of square meters in one hectare

Explanation: The formula calculates how many planting positions fit into one hectare based on the specified spacing.

3. Importance of Proper Tree Spacing

Details: Proper spacing affects tree health, yield, and ease of maintenance. Too close reduces growth, too far wastes land. Optimal spacing varies by species and purpose (timber vs. fruit production).

4. Using the Calculator

Tips: Enter row spacing and tree spacing in meters. Both values must be positive numbers. Common spacings range from 1-10 meters depending on tree type.

5. Frequently Asked Questions (FAQ)

Q1: What's typical spacing for pine plantations?
A: In NZ, radiata pine is often planted at 3m between rows and 2m within rows (1667 trees/ha).

Q2: How does spacing affect tree growth?
A: Closer spacing leads to taller, straighter trees but smaller diameters. Wider spacing produces thicker trunks but more branching.

Q3: What spacing for orchard trees?
A: Fruit trees typically need 4-6m spacing (400-700 trees/ha) to allow for canopy growth and machinery access.

Q4: How to account for terrain?
A: On slopes, row spacing may follow contours. Adjust calculations for non-rectangular plantings.

Q5: What about planting in triangles?
A: Triangular planting fits 15% more trees per hectare at same spacing. Multiply rectangular result by 1.15.
