Where are all the trees?

Every single map I generate has no trees.
Now, I don't now if this has been discussed before because my search for the topic has ended up with no helpful results.
I know there's probably something really simple that I'm forgetting, but I just downloaded this game last night, so I haven't the slightest clue what it might be. Help a noob out?

 

Yep, none. I've tried generating map after map and they all turn up completely flat (besides one or two craters) with no trees.

Not sure which part you wanted me to paste, but here you go.

Code:

# KAG Map Generator Config File
# map size is set in a console variables: m_width; m_height
# in Scripts/dedicated_autoconfig.gm or Scripts/autoconfig.gm

# Most noise variables (like persistence, lacunarity) are explained in the libnoise tutorial : http://libnoise.sourceforge.net/tutorials/tutorial4.html


baseline = 75                    # vertical percentage of map; vertical base line of ground; the higher percentage the lower the map starts

ground_noise_frequency = 35.0
ground_noise_lacunarity = 1.1              # less = less spikes
ground_noise_octaves = 4
ground_noise_persistence = 0.5

hill_height_max = 7                     # in tiles

mountain_concentration = 23; 45; 55; 77;       # horizontal percentage of map
mountain_width = 10                           # horizontal percentage of map
mountain_height = 10                       # in tiles
mountain_shape = 1                            # 0 - straight; 1 - convex; 2 - concave

hole_concentration = 50;                # horizontal percentage of map
hole_width = 6                           # horizontal percentage of map
hole_height = 44                       # in tiles
hole_shape = 1                            # 0 - straight; 1 - convex; 2 - concave

respawn_spots = 15; 85;                       # horizontal percentage of map

gold_concentration = 50;                   # horizontal percentage of map

cave_noise_frequency = 2.0
cave_noise_lacunarity = 1.6             
cave_noise_octaves = 5
cave_noise_persistence = 1.55
cave_turbulence_power = 0.1
cave_turbulence_roughness = 8.0
cave_turbulence_frequency = 4.0

stone_noise_frequency = 20.0
stone_noise_lacunarity = 1.6
stone_noise_octaves = 6
stone_noise_persistence = 1.0
stone_multiplier_mountain = 0
stone_multiplier_hole = 12
stone_cave_thickness = 1          # thickness of stone around caves; 0 - stone does not concentrate on caves

gold_noise_frequency = 13.0
gold_noise_lacunarity = 1.4             
gold_noise_octaves = 5
gold_noise_persistence = 1.1
gold_turbulence_power = 0.15
gold_turbulence_roughness = 9.99
gold_turbulence_frequency = 6.5

wood_tree_maxheight = 15
wood_tree_variation = 4                   
wood_noise_frequency = 15.0
wood_noise_lacunarity = 1.5
wood_noise_octaves = 3

I usually just use the default settings for map generating.

This is what all the maps look like for me (the only thing that differs for each new gen is the caves).

The only error I get is one that tells me my server can't access the internet due to firewall restrictions (which I will take care of soon), but I doubt that would affect anything.

 

Aha! I've figured it out, the generator script I was using was the "generator_flat" one. I switched it to the normal "generator", and I have trees now! Thank you for your help :)
